Foreword The 1980s were turbulent for the domestic nonferrous metals industries. Many mines and plants were closed during the decade, because of a variety of factors including aging facilities, environmental regulations, and low metals prices. The corporate structures of the industries also changed drastically as companies bought, sold, and merged businesses in order to become more competitive. OTA examined the copper sector of the nonferrous industry in its 1988 report Copper: Technology and Competitiveness. That report describes the conditions the copper industry faced during the early 1980s. It documents the steps U.S. copper companies took to improve their position in the mid1980s, and evaluates the industrys present and possible future status. This paper, requested by the Subcommittee on Mineral Resources Development and Production of the Senate Cornrnittee on Energy and Natural Resources extends the analysis of the earlier report. This report profiles the structures of four domestic nonferrous metals industries (copper, alumin urn, lead, and zinc) and the changes they have undergone since 1980. The study also outlines the U.S. position in the world markets. The study found that the four industries are not homogeneous. They are distinct with each having its own experiences, problems, and structure. The copper industry had many temporary mine and plant closures during the 1980s, but rebounded late in the decade as a result of cost cutting programs and high copper prices. Though there were major changes in copper mine and plant ownership, most of the shifts consolidated assets among existing producers. There were, however, major changes in the ownership of the companies themselves. The last al uminum smelter built in the United States opened in 1980. Since then, about 20 percent of U.S. capacity has closed. The four major U.S. firms have emphasized the fabrication sector of the business in the United States and expanded their primary aluminum capacity overseas. In the lead industry, much of the mine and plant capacity changed ownership in the 1980s. kad production declined by about a quarter to a third in the various primary sectors of the industry. The secondary (recycled) lead sector, which now accounts for 65 percent of domestic lead production, is a major influence on the market. Much of the primary zinc industry also changed ownership during the decade. The zinc processing sector experienced the greatest decline of the four industries. Its decline started in the mid1970s. The outlook for lead and zinc has improved somewhat in recent years. Several new mines opened late in the decade. The Red Dog, Alaska mine (slated to open in 1990) will greatly increase the U.S. presence in lead and zinc mining industries.

Chapter 1 Introduction The 1980s were turbulent for the domestic nonferrous metals industries. Many mines and plants were closed-some temporarily, some permanently-for a variety of reasons including aging facilities, environmental regulations, and low metals prices. The corporate structures of the industries also changed drastically during the decade. Companies bought, sold, and merged businesses in order to become more competitive. This report profiles four domestic nonferrous metals industries (copper, aluminum, lead, and zinc) and the changes they have undergone since 1980. SCOPE The report focuses on the primary sectors of the four industries, little discussion is given to the secondary (recycling) sectors. Unless noted otherwise, prices, costs, and expenditures are in nominal (current) U.S. dollars, and global production and consumption figures refer to the nonsocialist world (NSW).1 All tonnage figures are in metric tomes (1 metric tonne= 1.1 short tons = 2,204.6 pounds). Companies are usually identified by their common abbreviations. Their full names, headquarters locations, major nonferrous metals affiliates, and principal countries of operation are listed in appendixes B and C. BACKGROUND The dominant feature of the nonferrous markets in the past decade was the global slowdown in demand growth. Following the oil shocks of the 1970s, metals use grew at much slower rates than had been common earlier in the post-war period (see figure l-l). Consumption growth rates declined several percentage points for each of the four metals in this study. The annual growth rates in NSW consumption during 1950-74 and 1979-88 were as follows: 1950-74 1979-88 Copper . . . . 3.9% 1.1 % Aluminum . . . . 9.0% 2.3% Lead . . . . . 2.7% 0.5% Zinc . . . . . 3.9% 1.2% This long-term (secular) slowdown affected metals producers worldwide not just in the United States. U.S. metals producers faced other challenges, in addition to the demand slowdown, during the 1980s. In some cases, these problems had their beginnings 20 or 30 years prior. Since World War II, the United States has seen its dominance in the production of many nonferrous metals d iminish greatly. In 1950, almost half of the NSWS output of refined copper, al uminum, and zinc, and over a quarter of its lead came from the United States. 2 The dominance of U.S. companies was made even greater by their many foreign affiliates. By 1980, the U.S. share for refined metal production had declined to 24 percent for copper, 36 percent for alumin um, and 8 percent for zinc. The U.S. share of the lead market increased to 28 percent, because of the opening of the Viburnum Trend in Missouri. Production grew overseas faster than in the United States for a variety of reasons. New deposits were discovered in relatively unexplored foreign regions (e.g., Australia and Brazil). Processing plants were built overseas to keep costs low, to fiulfill countries development plans, and to be near growing markets. For example, the development of abundant low-cost power lured aluminum ~ production to Australia, Canada, Brazil, and Venezuela. The rebuilding of the war torn countries, and the general economic development of others, caused the overseas markets for metals to grew faster than the North American market. 3 1~ NW ~rnp~es ~ co~~es with market economies (including Yugoslavia).

Their metals fabrication sectors (the principal markets for metals) were developed for the purpose of making products for both domestic use and export. l

Chapter I-Introduction l 3 U.S. dominance was also weakened by the iiagrnentation of the metals markets. Many companies independent of U.S.-based multinationals began producing nonferrous metals. Among these were State-owned operations and custom smelters/ refiners. 4 These companies complicate the markets because they have goals that often diverge from those of the traditional integrated producers. The industry was also shaken up by the entrance of non-mining firms (e.g., oil companies). There was also direct market intervention (stockpile transactions and price controls) taken by the U.S. Government. Such actions, along with the establishment of floating exchange rates, caused metals prices to become more volatile. This made planning more difficult and the business generally more risky. High production costs also plagued the U.S. industry. In the copper and zinc industries, the United States was in danger of becoming a marginal producer. Labor, energy, and environmental compliance costs increased during the 1970s especially. Productivity at U.S. mines and plants had not increased enough to offset the increased costs. Domestic facilities were mostly older and in great need of modernization. COPPER The United States is currently the NSWS largest copper refiner, and second largest miner and primary smelter. Most of the production comes from Arizona, New Mexico, Utah, Michigan, and Montana. The principal foreign competitors are in less developed countries (Chile, Zambia, Zaire, and Peru). Except in Peru, the largest companies in these countries are state-owned. In the 1980s, the domestic copper industry experienced many difficult years when prices and production levels were both low. Prices ranged from $0.66 to $0.77flb during 1982-86. U.S. primary copper production remained in the 1.0 to 1.2 million tonnes per year (tpy) range during 1982-87. The market began recovering in 1987. In 1989, prices rose to $1.31/lb and production increased to 1.5 million tonnes. The production levels at the end of the 1980s were comparable to those of the late 1970s, except in the smelting sector which had declined signicantly (see table l-l). Over the 1979-89 period, production was up 4 percent at mines, down 16 percent at smelters, down 3 percent at primary refineries, and up 7 percent at secondary plants. In comparison, production elsewhere in the NSW increased between 13 and 20 percent in the various primary sectors and 41 percent in the secondary sector during 1979-88 (see table 1-2). Four major new domestic copper-producing mines opened during the decade (see table l-l). Five mines closed permanently and many more were closed temporarily because of low prices, strikes, and modernization shutdowns. From March 1981 to January 1983,28 domestic mines closed or cut back production and U.S. mine capacity utilization hovered around 65 percent. 5 In the processing sector, five smelters and three refineries (electrolytic and fire refineries) closed permanently. No greenfield plants opened, but several existing facilities underwent substantial modernization. G Environmental regulations and aging facilities were major causes of the decline in this sector. The picture was more positive in the electrowinning sector, seven facilities opened, five closed, and many were expanded. The number of companies involved in the U.S. copper industry declined during the 1980s. Large producers such as Anaconda Copper, Amax, Duval, Inspiration, Cities Service, and Noranda left the industry while only Montana Resources and Cox Creek Refining entered. Major changes occurred in the ownership of severaI of the major producers. Cyprus was spun off from Amoco in 1985. Magma was spun off from Newmont in 1987. Copper Range changed hands several times before it was bought by Metall Mining (a Canadian subsidiary of Metallgesellschaft) in 1989. Kemecott was acquired by SOHIO (a subsidiary of British Petroleum) in 1981 and then sold to London-based RTZ (the worlds largest minerals firm) in 1989. Five companies (Phelps Dodge, Magma, Cyprus, Kemecott, and Asarco) currently account for most of the primary copper production in the United ~stom smelters/refmers process concentrates (or other intermediate materials) produced by other companies. The feed material is either bought or tolled. In the case of tolling, the material is processed for a fee, but does not change ownership. W.S.

Chapter 1-Introduction l 5 States. They are integrated producers that have been producing copper for many years. Most of their mines, smelters, and refineries are in the United States. Their strategies generally emphasize lowcost production and, except for Asarco, specialization in copper rather than broad-based minerals activities. 7 Over the last decade, these companies cut their costs drastically. Some of the measures (e.g., delayed maintenance) yielded short-term cost gains, but many resulted in permanent savings. Wage rates were renegotiated, and in some cases tied to metals prices. The number of workers was also cut. In addition, a great amount of money was invested to modernize mines and plants. As a result, the domestic industry is now relatively cost competitive and among the worlds most modern. It is the leader in the use of low-cost solvent extraction-electro winning (SX-EW) technology. Little of the recent U.S. investment has gone into either exploration or research and development (R&D). Exploration has been limited because of the financial risk of building new mines, especially when several large new projects (e.g., Olympic Dam in Australia and Neves Corvo in Portugal) have recently come on stream and several others are expected soon (e.g., La Escondida in Chile and Salobo in Brazil). R&D efforts are also minimal. The general feeling is that technology transfers too quickly in the industry to allow any particular company to make exclusive gains from R&D. The problem is particularly acute in the area of product development. Little attention is paid to product differentiation. Copper is seen basically as a commodity, with consumers basing their purchase decisions almost solely on price. Acid rain legislation tops the list of the industrys environmental concerns. U.S. copper producers feel they contribute little to overall sulfur dioxide (SO 2 ) emissions, and the associated acid rain, and therefore should not be subjected to more stringent regulations. They also argue that they have already invested greatly to reduce their SO 2 emissions under legislation enacted in the 1970s. Producers are also concerned about increases in energy costs that would result from energy utilities compliance with potential regulations in this area. ALUMINUM The United States mines little bauxite, but is currently the NSWs second largest alumina refiner and largest aluminum smelter. 8 Except for one plant in the Virgin Islands, all of the domestic alumina refineries are located near the Gulf Coast. The smelter capacity is located primarily in the Pacific Northwest and the Ohio Valley, but also in the Carolinas, New York, and Texas. The major foreign producers are in Western Europe, Canada, Australia, Brazil, and Venezuela. Most of the industrys new capacity is being built in the latter four countries, because of their abundant, low-priced electricity. The cost and availability of electricity, which accounts for about one-third of primary aluminum production costs, are principal factors in the siting of new smelters and the competitiveness of existing smelters. 9 The U.S. aluminum market went through several cycles during the decade. Prices fluctuated between $0.47/lb and $0.76/lb in the 1980-87 period, but ended the decade somewhat higher ($1.10/lb in 1988 and $0.89/lb in 1989). U.S. primary aluminum production fell as low as 3.0 million tpy (in 1986), but recovered to around 4.0 million tpy in 1988-89. Primary production in 1989 was 12 percent lower than that in 1979. Secondary production, however, was up 20 percent over the same period. In other NSW countries, primary aluminum production increased 34 percent and secondary production increased 46 percent during 1979-88. During the decade, four alumin a refineries and ten al uminum smelters closed. More smelters were closed temporarily at various times, because of low prices. The only new facility to open was the Mount Holly, South Carolina smelter which began production in 1980. Three companies (Conalco, Anaconda Aluminum, and Revere Copper and Brass) left the U.S. industry during the 1980s.

6 l Nonferrous Metals: Industry Structure independent producer. Six companies (Columbia Aluminum, Columbia Falls, Alcan, Vanalco, Ravenswood, and Northwest Aluminum) entered U.S. industry in the 1980s. A seventh (Ornet) was essentially new to the industry also. It was sold to its current owners, Ohio River Associates, in 1986. The U.S. majors (Alcoa, Reynolds, Alumax, and Kaiser) operate almost two-thirds of U.S. smelter capacity. They are multinationals with al uminum smelters and fabricating plants all over the world. Except for Alumax, they all own bauxite mines and alumin a refineries. Most of these companies recent investment in the primary aluminum sector have been in overseas facilities. For example, Alcoa is investing in Australia, and Reynolds and Alumax are spending in Canada. In the United States, they are emphasizing the fabricating end of the business (cans, foil, packaging, architectural products, etc.). 10 All four companies invest heavily in R&D for these more value-added products. The remaining one-third of U.S. aluminum smelter capacity is operated by two Canadian firms and seven independents. The Canada-based firms are Alcan and Noranda. The independents are Ormet, Southwire, Columbia Aluminum, Columbia Falls, Vanalco, Ravenswood, and Northwest Aluminum. Except for Southwire, all were formed in the 1980s. Recycling is an important factor in the U.S. al uminum industry. The production of secondary al uminum consumes about 90 to 95 percent less energy than does primary aluminum. About 60 percent of secondary aluminum recovered from old scrap comes from used beverage containers (UBC). In 1988, the UBC recycling rate was about 55 percent in the United States. Most UBC is recycled by alumin um sheet producers, many of which are also primary alumin um companies. Industrial scrap is processed by secondary smelters. About 40 secondary alumin um producers are in operation in the United States. Acid rain legislation, because of its effects on the electric utilities, is the principal environmental concern of the aluminum industry. All proposed SO 2 emissions regulations will raise costs at coal-based utilities to some degree. The extent to which the cost increases will be passed on to aluminum smelters is uncertain. The impact will be mitigated somewhat by the variable rate contracts that tie electricity rates to the price of aluminum. A U.S. Bureau of Mines study of 10 domestic smelters found that the various acid rain proposals would increase their electricity rates by 3.5 to 5.5 mills/kWh and increase their costs by an estimated 2.5 to 4/lb of aluminum. 11 The increases, however, are very site-specific. In Ohio and West Virginia, costs would increase 5.2 to 7.7/lb; in other regions, the effects would be smaller. Smelters tied to hydropower utilities would see minimal rate increases. The 10 smelters studied account for 90 percent of the alumin um capacity that is tied to coal-fried generating facilities-those most liable to experience cost increases from acid rain legislation. 12 They account for about half of domestic aluminum capacity overall. LEAD The United States is a major producer of lead. It currently ranks second in the NSW in mine output and first in refined lead production. The principal mines and plants are in southeastern Missouris Viburnum Trend. There are additional leadproducing mines in Colorado, Idaho, Montana, and Alaska, and processing facilities in Montana and Nebraska. The main integrated foreign competitors are Australia, Canada, and Mexico. In addition, Peru is a major mining country, and Western European countries and Japan have large processing sectors. The U.S. lead industry faced hard times in the mid-1980s. Lead prices started the decade at around $0.43/lb, fluctuated downward to $0.19/lb in 1985, and then recovered to the $0.35 to $0.49/lb range in 1987-89. Production of primary lead declined over the decade. During 1979-89, U.S. mine production declined 24 percent and primary metal production fell 31 percent. Secondary production declined in the early 1980s, but rose later in the decade to nearly match its 1979 level. In other nonsocialist countries, t~e majom ~ve not, however, abandoned tdl of tieh dommtic P~ uminum capacity. It helps them manage their business risk. llne smelters studied were Sebree, KY (Alcan); Frederick, m (AIWIMX ); Mt.

Chapter 1-Introduction l 7 primary production held fairly steady and secondary production rose 11 percent during 1979-88. Six new lead-producing mines opened during the decade. 13 Two mines that produced lead were permanently closed. Many more mines closed temporarily at some time during the 1980s, because of low prices. In the processing sector, two smelters and one refinery were closed permanently and no new ones opened. Much of the U.S. primary lead industry changed ownership during the 1980s. Ten firms (Doe Run, Asarco, Cominco-Dresser, Montana Tunnels, Greens Creek, Washington Mining, Hecla, Bunker Hill Mining, Star-Phoenix Mining, and New Butte Mining) currently mine lead in the United States. Only Doe Run and Asarco operate smelting/refining facilities. Cominco-Alaska will operate the new Red Dog zinc-lead mine in Alaska. The mine is slated to open in 1990. The project is a joint venture between Cominco (a Canada-based multinational minerals producer) and NANA (an Alaskan Native corporation) which owns the mineral rights to the property. Red Dog is being developed primarily for its zinc. However, at full capacity it will be the United States third or fourth largest lead-producing mine and will increase domestic production by 16 percent over 1989 levels. The mine will ship its concentrates to British Columbia, the Far East, and Europe for processing. Leads health effects are the industrys most important environmental issue. Health concerns have weakened demand for the metal in some sectors (e.g., gasoline additives, indoor paints, and various building products). There is also concern regarding the health and safety of workers exposed to lead particulate during the production process. Most of the industry is not in compliance with the current National Ambient Air Quality Standards (NAAQS) particulate standard for lead. 14 Compared with other metals industries, lead has a relatively easy time meeting the SO 2 emissions standards of the Clean Air Act. The economics of sulfur recovery are further aided by existence of large nearby sulfuric acid markets. However, one of the four existing primary smelters does not have an acid plant, and could be forced to close in the not-too-distant future under contemplated regulations. Currently, about 65 percent of U.S. refinery output is secondary lead. Lead acid batteries account for 85 percent of total recycled lead material at domestic secondary plants. The major secondary smelters in the United States are RSR Corp., Pacific Dunlop/GNB Battery, Schuylkill Metals, Exide Corp. Battery, and Sanders Lead, which represent over 70 percent of domestic capacity. Environmental factors caused recycling to become more difficult in the 1980s. Spent lead batteries are classified by the U.S. Environmental Protection Agency (EPA) as hazardous waste under the Resource Conservation and Recovery Act (RCRA). Many scrap collectors and dealers refuse to handle batteries for fear of incurrin g liability under Superfund. 15 However, the integrated metal producers, battery manufacturers, and large independent smelters have backward integrated into this market segment to a large degree. ZINC The United States is a relatively small zinc producer. In the NSW, it ranks sixth in mine production, eighth in primary refinery production, and first in secondary output. The principal zinc mining State is Tennessee. It accounts for over half of U.S. production. Additional zinc-producing mines are located in Missouri, Colorado, Alaska, Idaho, Montana, New York, and Nevada. About 20 percent of total zinc production comes as a byproduct of Missouri lead mines, but most comes from mines where lead is of minor importance. Processing facilities are located in Tennessee, Pennsylvania, Oklahoma, and Illinois. The main foreign integrated producers are Canada, Australia, and Western European countries. In addition, Peru and Mexico are major mining countries, and Japan has a large processing sector.

8 Nonferrous Metals: Industry Structure Zinc prices, unlike those of copper, aluminum, and lead, fluctuated upward during the 1980s. The price of zinc remained above its 1980 level of $0.36/lb for the entire decade. Prices rose their greatest in the later years, when they increased from $0.38/lb (1986) to $0.82/lb (1989). U.S. secondary production rose during the decade, but primary output fell. Compared with 1979 levels, U.S. production in 1989 was down 5 percent in mining, down 47 percent in primary slab processing, and up 107 percent in secondary slab processing. In other nonsocialist countries, production increased 11, 18, and 9 percent in the mining, primary slab, and secondary slab sectors respectively during 1979-88. In the United States, one new zinc mine (Pierrepont) and two zinc-producing precious metals mines (Greens Creek and Montana Tunnels) opened during the decade. In addition, zinc is recovered from the West Fork lead mine which opened in 1985. Five zinc mines, and one zinc-producing precious metals mine, were permanently closed during the 1980s. In the processing sector, three smelter/refineries were closed permanently and no new ones opened. As in industry Fourteen Miniere, the lead industry, much of the U.S. zinc changed ownership during the 1980s. firms (Zinc Corp. of America, Jersey Big River, Asarco, Alta Gold, ComincoDresser, Doe Run, Montana Tunnels, Greens Creek, Hecla, Washington Mining, Bunker Hill Mining, Star-Phoenix Mining, and New Butte Mining) currently produce primary zinc in the United States. Only the first three operate primary smelting/ refining zinc facilities. All but Big River operate mines. When it opens in 1990, the Cominco-NANA Red Dog mine will greatly boost the United States stature as a zinc producer. At capacity, it will be the worlds largest zinc mine and nearly double U.S. zinc mine production over 1989 levels. The decline in the U.S. zinc industry during the last two decades has been more pronounced than in the copper, aluminum, and lead industries. Primary slab zinc capacity fell from 980,000 tomes in 1970 to 570,000 tonnes in 1980 to 320,000 tomes in 1988. The closures were the result of declining local supplies of concentrates, rising energy (primarily natural gas) costs and environmental regulations. 16 Compliance with environmental regulations does not appear to constitute a major competitive disadvantage to current U.S. producers .17 Of the four primary slab plants that remain, three are electrolytic plants which are relatively easy to modify to meet environmental standards.

Chapter 2 Copper Industry INTRODUCTION Copper has been used in jewelry, utensils, weapons, and tools for thousands of years. Such objects were hammered from native copper-the naturally occurring pure metal-in areas around the Mediterranean Sea and Lake Superior as long ago as 6000-5000 BC. The metal was first smelted from ores around 4000-3500 BC. Ancient mines have been found in Israel, Cyprus, Spain, and Britain. The Industrial Revolution and the created the need for a highly industry. use s age of electricity developed copper Coppers excellent electrical conductivity makes it important for power, lighting, and communications. In addition, its strength, durability, malleability, and resistance to corrosion and fatigue make it useful in a variety of structural applications. In the United States, the largest market for copper is the construction industry. An estimated 41 percent of domestic copper mill shipments went to this industry in 1988. 1 Uses there include electrical wiring, plumbing and heating, air-conditioning and refrigeration, and architectural applications (e.g., gutters and roof and wall cladding). The second largest market (22 percent of shipments) was the electrical and electronics industry for uses such as telecommunications, power utilities, industrial controls, business electronics, and lighting and wiring. Other major markets include the industrial machinery and equipment industry (14 percent), the transportation sector (12 percent), miscellaneous consumer goods (e.g., appliances, cooking utensils, jewelry, and objets dart), military applications, coinage, pharmaceuticals, and chemicals. Across all markets, copper is used primarily for electrical and electronic applications. Copper use in these applications accounted for 70 percent apparent domestic consumption in 1988. 2 Production Methods and Technologies of Modern copper production techniques were established around 1900. Until then, only very rich ores (those containin g 5 to 30 percent copper) could be processed economically. The commercial exploitation of lower grade ores became possible with the development of precipitation and flotation technologies and large-scale mining and processing methods. Today, most copper comes from ores containing 0.5 to 2 percent copper. Copper is produced primarily from sulfide minerals such as chalcopyrite (CuFeS 2 ), chalcocite (C u 2 S), bornite (Cu 2 Fe S 4 ), and covellite (CuS). Some production, though, is based on oxide minerals such as malachite (C u 2 (OH ) 2 C O 3 ), azurit e (CuSi O 3 ), chrysocolla (C u 3 (OH ) 2 (C 0 3 ) 2 ), and cuprite (Cu 2 O). Copper ore may be mined by either open pit, underground, or solution mining methods. Open pit mines account for about 60 percent of nonsocialist world (NSW) production and 85 percent of U.S. production. Copper is extracted from the ore by two principal methods: pyrometallurgical (concentration-smelting-refining) and hydrometallurgical (leaching-solvent extraction-electrowin ning). The pyrometallurgical route is the more common production method. The first step, ore concentration, occurs at the minesite. It involves crushing, grinding, and flotation of the ore into concentrates which contain 20 to 30 percent copper. Concentrates are the crudest intermediate product that is marketed. The next processing steps (roasting, smelting, and converting) are performed at the smelter. 4 Roasting is an optional step which is sometimes used to upgrade the concentrates.

10 l Nonferrous Metals: Industry Structure complex minerals to produce a liquid copper-sulfide matte (35 to 75 percent copper). There are four basic smelting technologies: flash, reverberatory, electric, and continuous. 5 Converting, usually carried out in a Pierce-Smith converter, oxidizes the matte into blister copper (98.5 to 99.5 percent copper). Environmental regulations and process economics make the control of sulfur dioxide (SO 2 ) gas a very important aspect of the various smelting processes. In recent years, concerns about the air quality impacts of reverberatory furnaces have led to the widespread adoption of electric and flash furnaces in the United States. Most of the impurities remaining in the blister copper are removed at the refinery. First, the molten blister copper is fire-refined (to further reduce its sulfur and oxygen content) and then cast into anodes. The anodes are then electrolytically refined (electrorefined). They are hung vertically between cathode starter sheets in long tanks (cells) filled with an acidic copper sulfate solution. An electric current is run through the solution (between the electrodes) and the copper gradually corrodes from the anode and plates onto the cathode. The end product, cathode copper, is 99.99+ percent copper. Cathodes are melted and cast into wirebar or continuous bar stock (for wire manufacture), slabs (for mechanical use), or ingots (for alloying). In the hydrometallurgical production route, copper is recovered from the ores using aqueous (water-based) solutions. This method is applied mainly to oxide ores, and to low-grade oxide and sulfide mine wastes. 6 It is a very low-cost method of producing copper. When mining costs are excluded (or nonexistent as in the case of waste dump leaching), copper can be produced for around $0.30/lb. In 1988, about 16 percent of domestic primary copper output was produced by hydrometallurgical techniques. The first step, leaching, involves percolating sulfuric acid (H 2 SO 4 ) through the ore or waste. The acid (leachate) dissolves the copper minerals and carries them away. The copper is recovered by solvent extraction and electrowinning (SX-EW). 7 I n solvent extraction, an organic chemical that dissolves copper but not impurity metals is mixed with the leachate. 8 The organic solution collects the copper and is then treated with sulfuric acid (H 2 SO 4 ) to strip the copper into an electrolytic solution. Copper is recovered from the electrolyte by electrowinning, a process similar in principal to electrorefining (described above). The main difference is with the anodes. Electrow inning uses inert (nondissolving) anodes since the copper is already in the electrolyte. Application of the electric current deposits the copper on to the cathode. The cathode copper is then stripped from the starter sheets (which are reused), and shipped to the rod mill or fabricator. THE 1980s The U.S. copper market started the 1980s in a shortage situation (see figures 2-1 and 2-2). In 1980, domestic primary copper production (1.2 million tonnes) was low and prices (averaging $1.01/lb) were high compared with previous years. Production increased in 1981, but then fell to the 1.0 to 1.2 million tonnes per year (tpy) range during 1982-87. Prices were also low in this period. They averaged $0.75/lb in 1982-83 and $0.67/lb in 1984-86. These prices were similar in nominal terms to those of the sFIzsh process~ (IUCO ad CMohunpu) combine roasting and hearth smelting. The sulfide particles in the cOn=nt@tX r-et witi an fi/oxYgm mixture to produce a large proportion of the thermal energy needed for smelting. As a result flash furnaces have relatively low fuel costs. Further, their waste gases are rich in SOZ, permitting economic pollution controLThe reverberatory procms was widely favored over the last 50 to 60 years because of its versatility; all types of material, lumpy or free, wet or dry, could be smelted. However, the reverberatory furmce has relatively high fuel requirements, and its sulfur dioxide gas is too dilute for economic conversion into sulfuric acid or treatment with other pollution control methods.The electric process uses an electrically heated hearth furmce that is similar in operation to the reverberatory furnace, but with more advantageous control of tbe effluent gases. The process makes limited use of heat generation from sulflde oxidatioq and the heavy reliance on external energy can result in relatively high energy costs. Two continuous processes (Noranda and Mitsubishi) are in limited use. They combine roasting, smelting, and converting in one operation that produces blister copper directly from concentrates, while taking advantage of the heat generated by the oxi&tion of sullldes. The benefits of continuous processes include lower capital cost, reduced materiak handling, low heat losses, very low energy requirements, econoznical sulfur dioxide gas recovery, and the ability to apply online computer controls to the entire copper-making process. Neither of these processes, however, has yet proven to be truly continuous. Their slags, which have high copper contents and must be recyclm can only be processed with auxiliary equipment.

This includes IMhMdly oc caning oxide ores and sul.tide ores that have been oxidized by the atmosphere (e.g., in waste dumps) or by roasting. Similar processes for sultldes and complex ores are still being developed.

In 1989, production had reached 1.5 million tonnes and prices had risen to $1.32/lb in 1989. U.S. production of secondary (scrap-based) copper followed a similar pattern to that of primary copper. It started the decade around 470,000 tpy, fell to 310,000 tomes in 1984, and then recovered to 500,000 tonnes in 1989. Over the entire decade, secondary material accounted for 26 percent of total U.S. refined copper production (compared with 20 percent in 1975 -79).9 The United States consumed 1.9 million tonnes of copper in 1980. 10 Consumption rose in 1981, but then fell to 1.7 million tonnes in 1982 (a recession year). In 1983, consumption increased even though production continued to fall. By 1985, consumption had risen to 2.1 million tpy. It has grown an average of 1.3 percent per year since. The difference between consumption and total refined production changed greatly over the decade. This gap, which is met with imports or inventory reductions, grew from 165,000 Figure 2-2U.S. Copper Production and Consumption, 1975-89 Million of tonnes 2.5 2.0 1.5 1.0 0.5 0.0 75-79 80 81 82 83 84 85 86 87 88 8 9 Year W Mine production = Primary production [ ) Secondary production Consumption NOTE: Secondary production is refined metal recovered from old and new scrap.

The gap narrowed somewhat in 1988-89. For the nonsocialist world (NSW) as a whole, copper production and consumption were relatively stable during the 1980s (see figure 2-3). Over the period 1980-88, primary refined production grew at annual rate of 1.5 percent and consumption rose at a rate of 1.9 percent. Secondary production averaged 17 percent of total NSW refined copper production. The openings, closings, and ownership changes that occurred in the U.S. primary copper industry during the 1980s are profiled in table 2-1. Three new copper mines (Troy, Pines Altos, Miami) opened during the decade. A lead mine (Casteel) which produces copper also opened. Five mines (Sacaton, Copperhill, Magma, New Cornelia, and Continental) closed permanently during the 1980s. Many more mines closed temporarily at some time during the 1980s because of low prices, strikes, and modernization shutdowns.

No greenfield plants were constructed, but several new facilities were built at existing sites (the Hayden smelter, the Sam Manuel smelter, and the White Pine refinery). There is talk, however, of building a new smelter in Texas in the early 1990s. The picture was more positive in the electrowinnin g sector, seven facilities opened and five closed. In addition, existing facilities were expanded. Electrowinning production grew from 118,000 tonnes in 1980 to 228,000 tonnes in 1988 and the expansion is continuing. During 1980-88, U.S. smelter capacity declined 36 percent to 1.2 million tonnes, electrolytic refining capacity fell 22 percent to 1.6 million tonnes, and electrowinnin g capacity rose 57 percent to 300,000 tonnes. The number of companies involved in the U.S. copper industry declined during the 1980s. Large producers such as Amax, Anaconda Copper, Cities Service, Duval, Inspiration, and Noranda left the industry. All of their facilities, except for one mine and one refinery, were purchased by existing copper producers. Montana Resources and Cox Creek Refining were the only new companies to enter the industry. Major changes occurred in the ownership of many producers. Cyprus was spun off from Amoco in 1985. Magma was spun off from Newmont in 1987. Copper Range changed hands several times before it was bought by Metall Mining in 1989. Kennecott was acquired by SOHIO (a subsidiary of British Petroleum) in 1981 and then sold to RTZ in 1989. PRODUCER PROFILES, 1990 Chile and the United States dominate all sectors of the primary copper industry: mining, smelting, and refining (see figure 2-4). They have been the industry leaders for much of this century. Japan, the third ranked smelting and refining country, has little mine capacity and relies on imports of concentrates to feed its industry. The medium-sized producers are Canada, Zambia, and Zaire. Together, these six countries control about two-thirds of the NSW primary copper output. The United States, Japan, and Western European countries are the largest secondary copper producers. Less developed countries (LDCs) play a larger role in the copper industry than in the aluminum, lead, and zinc industries. Chile, Zambia, Zaire, Peru, Mexico, and the Philippines are involved in all aspects of the primary copper industry, not just the mining sector. In 1988, developing countries world accounted for 57, 48, and 39 percent of NSW mine, smelter, and refinery production respectively.

16 l Nonferrous Metals: Industry Structure technology, and the establishment of good management practice make U.S. mines and mills among the most productive in the world in terms of workhours per tonne of ore. In this regard, U.S. facilities improved dramatically in the 1980s. There are currently eight domestic primary smelters in operation. Reverberatory smelting furnaces are used at El Paso (Asarco) and White Pine (Copper Range). The one electric furnace smelter, Miami (Cyprus), has been among the most costly of the domestic plants to operate because of high electricity rates. Newer, more efficient, flash furnaces are used at Hayden (Asarco), San Manuel (Magma), and Chino and Hidalgo (Phelps Dodge). The Noranda continuous process is used at the Garfield (Kennecott) smelter. Smelting in the United States is characterized by stringent air pollution controls and, until recently, an unattractive sulfuric acid market. 16 There are currently eight electrolytic and twelve electrowinning refineries in operation operating in the United States. In 1988, approximately 16 percent of U.S. refined production came from the electrowinning process. Leaching and SX-EW technologies, because of their low costs, were an important aspect in the U.S. industrys financial turnaround in the late 1980s. The United States is the worlds largest secondary copper producer. The secondary sector accounted for about a quarter of total domestic production in 1988. There are five secondary smelters, two electrolytic refineries, and six fire refineries in operation. Seven domestic companies (Phelps Dodge, Cyprus, Magma, Asarco, Montana Resources, Cox Creek, and Southwire) and two European firms (RTZ and Metallgesellschaft) have major holdings in the primary copper industry in the United States (see figure 2-5). In addition, two Japanese firms (Mitsubishi and Sumitomo) have partial holdings in U.S. mines. Phelps Dodge Phelps Dodge is North Americas largest, and the worlds second largest, copper miner. 17 In 1988, it produced one-third of the copper mined and about a one-quarter of the copper smelted and refried in the United States. It is primarily a copper company, but it makes other products as well. The corporation is organized into two major divisions. The Mining division includes the companys domestic copper operations (from mining through rod production, marketing, and sales), the foreign mining operations and investments, and the exploration programs. In 1986-88, this division accounted for 62 percent of the companys revenues and 81 percent of its earnings. The other division, Industries, runs most of the corporations manufacturing operations. It includes Columbian Chemicals (a carbon black and synthetic iron oxide company), ACCURIDE (a steel wheel manufacturing company), and the Phelps Dodge Magnet Wire Co. It also includes interests in companies that produce wire, cable, and rod in 14 foreign countries. Phelps Dodges major domestic mines are Morenci/Metcalf in Arizona and Chino and Tyrone in New Mexico. Each mine has an associated electrow inning plant. The company owns smelters at Hurley (Chino) and Playas (Hildalgo) in New Mexico, and a refinery and rod mill at El Paso, Texas. Phelps Dodge has holdings in several foreign operations that produce primary copper. It owns 16 percent of the Southern Peru Copper Corp. (SPCC) which runs two copper mines and a smelter in Peru. Smaller amounts of copper are produced by the wholly owned Ojos del Salado copper-gold mines in northern Chile and the 45-percent-owned Black Mountain lead-silver-zinc-copper mine in South Africa. Phelps Dodge also has a feasibility study underway for the La Candelaria deposit in Chile. This mine could possibly be producing 100,000 tpy by the mid1990s. The companys domestic mines produce much more concentrate than its smelters can handle. In 1986, Phelps Dodge sold 15 percent of the Morenci mine to Sumitomo to divert some of the concentrate to Sumitomos smelters, and more importantly, to raise cash for restructuring programs. Mitsubishi owns one-third of the companys Chino mine and smelter. 18 16SMC acid is r~overed by tie fi-poflution control processes in copper smelting and is often sold as a byproduct or used in SX-EW opemtions. 17Among all NSW mining companies, Phelps Dodge ranks well behind Codelco (Chile), but just ahead of Gecamines (Zaire) and ZCCM (Zambia). It is the largest private producer, these other leading producers are all state-owned. In several years though the company will rank behind RTZ in mining, but not in the smelting/refiig seetor. 18A p~or Ower, Ke~eco~ sold a one.third fiterest in ~ of the output of Chino Mines to MC MiIlfXdS, a joint venhKe between Mitsubishi COW. and Mitsubishi Metal Corp. Phelps Dodge purchased the remaining two-thirds from Kennecott in 1986.

18 l Nonferrous Metals: Industry Structure and cable industry). The domestic continuous cast copper rod mills are in El Paso, Texas and Norwich, Connecticut. The rod production exceeds the companys internal sources of refined copper, so the supplies are supplemented with purchases. Phelps Dodge is credited with leading the U.S. copper industry out of the 1980s recession. It was the first company to deal aggressively with its unions, cut its costs, and return to profitability .20 Its business plan, in effect since 1984, has three elements. The frost is to reduce production costs in the copper operations and to enhance their profit margins rather than to maximiz e production. The second is to build and strengthen the non-copper businesses to help the company better withstand copper price swings. In this regard, the company stresses significant market share, internationally competitive costs and quality, specialized engineering capabilities, and stable earnings and cash flow. The third element is to strengthen the financial structure of the corporation. 21 Kennecott/RTZ Kennecott (owned by London-based RTZ) is the second largest copper mining company, and the fourth largest smelting and refining company, in the United States. The companys Bingham Canyon mine and its Garfield smelter and refinery are located in Utah. The Bingham Canyon mine, which underwent a $400 million modernization from 1985-87 under the ownership of BP America, is the largest copper mine in the country. RTZ obtained these facilities in 1989 when it purchased most of British Petroleums (BP) metals mining division. The operation was renamed Kennecott (after the company that ran the mine for much of this century). RTZ is one of the worlds largest metal mining corporations. It produces copper, aluminum, iron ore, lead, molybdenum, tin, zinc, gold, and silver at various subsidiaries and related companies throughout the world. It also produces energy (coal, oil, and uranium) and industrial products including borax, silica, specialty chemicals, fabricated and engineered products, and construction materials and services. In 1987, prior to the BP acquisition, RTZs earnings profile was: industrial sector (63 percent), metals sector (24 percent), and energy sector (13 percent). 22 RTZ s companies operate under a decentralized management style. The chief operating units are left to manage themselves under strategic guidelines that are agreed to every two years. 23 RTZs foreign copper holdings include Bougainville (PNG), Highland Valley (Canada), Palabora (South Africa), Somincor (Portugal) and ER&S (Australia). 24 It also has a 30 percent stake in the 300,000 tonne per year (tpy) Escondida project in Chile. With its acquisition of BP and its interests in these major new mines, RTZ will be the largest private copper mining company in the world (surpassing Phelps Dodge) in several years. It will be a somewhat smaller presence in the smelting/refining sector. Cyprus Cyprus is the third largest domestic copper mining company, but is smaller in the smelting and refining sectors. It has mines at Bagdad, Sierrita, Miami, Twin Buttes, Casa Grande, and Mineral Park in Arizona and Pines Altos in New Mexico. About a third of the mine production is oxide ore. The company has leaching and SX-EW facilities at five of its mines. It also has a roaster at Casa Grande which is used to prepare sulfide ore for leaching and SX-EW processing. In addition, there is a smelter, refinery, and a rod plant at Miami (Claypool), Arizona; and a rod plant in Chicago, Illinois. Until 1988, when Cyprus acquired the Miami facilities from Inspiration Copper, most of the companys copper concentrates were toll smelted under shortterm contracts. Now, about half of the concentrates are processed at the Miami smelter or the Casa Grande roaster. The remainder are smelted at Magmas San Manuel plant under a long-term contract. Cyprus, once the mining subsidiary of Amoco, was spun off as an independent company in July mphelps Dodge led the u.S. industrys drive to lower wages and relax work rules. In 1983, Phelps Dodge continued production despite a Pm1014@ strike at its facilities. Workers at the companys Arizona mines (at that time Morenci and New Comelia) and El Paso refinery voted against continued union representation in the fall of 1984.

Chapter 2-Copper Industry l 19 1985. Since then it has grown through a very aggressive acquisitions program. All of its copper properties, except Bagdad, have been purchased since the spinoff. It has acquired properties from Duval, Noranda, and Inspiration Copper. The company keeps its labor costs low by insisting prior to its acquisitions that the facilities be closed and the workers be terminated. When Cyprus takes possession of (and restarts) the mine or plant, it rehires the workers it needs without union contracts. Cyprus is strongest in the mining sector of the minerals business. Besides copper, Cyprus produces molybdenum, lithium, zinc, silver, gold, coal, and industrial minerals. It is the largest domestic producer of molybdenum, which it mines as a primary product in Nevada and Idaho and recovers from the copper ores at Sierrita (coproduct) and Bagdad (byproduct). The molybdenum processing facilities are in New Jersey. Cyprus acquired Foote Mineral, the largest NSW producer of lithium, from Newmont in 1988. The lithium mines are in Nevada and Chile, and the processing facilities are in Virginia, Pennsylvania, Tennessee, North Carolina, and Chile. Cyprus began recovering zinc and silver, as well as copper, from the Pines Altos mine in New Mexico in 1989. The company is evaluating a zinc-silver deposit in northern Mexico and a beryllium deposit in Texas. Copper and coal have been at the center of Cyprus business. During 1986-88, these two products accounted for about 80 percent of sales. However the proportions have changed significantly. In 1986, 50 percent of sales was from coal and 30 percent was from copper. In 1988, the proportions were reversed. Asarco Asarco is the second largest U.S. smelter and refiner and fourth largest miner. 25 It has copper mines at Ray and the Mission Complex in Arizona and at Troy in Montana. In addition, it owns half of the Butte, Montana mine. It has smelters at Hayden, Arizona and El Paso, Texas, and a refinery at Amarillo, Texas. Of the U.S. copper producers, Asarco is perhaps the most active in foreign projects. It is the majority shareholder (52 percent) in SPCC, the Peruvian copper mining and smelting concern. It also owns (through Medimsa) about 30 percent of Mexicana de Cobre which runs the La Caridad copper mine and Nacozari smelter in Mexico. Asarco also has ties to the Australian concern MINI, which owns copper facilities at Mt. Isa and has interests in base metal operations all over the world. Asarco owns 19 percent of MIM, and MIM owns 25 percent of Asarco. This link is a passive relationship that does not involve operational control. Asarco was originally a smelting and refining company. However, in recent years it has become more involved in the mining sector to ensure its supply of concentrates. It got caught short on its concentrate supplies in the 1980s and has been buying mines to prevent this from happening again. The company thinks the custom smelting and refining business has limited growth potential because there are fewer mines and mining companies today than in the past and plans to continue to make investments to increase its own mine production and expand ore reserves. 26 When the expansions are complete (in 1992), Asarco expects to have the capacity to provide all of the feed required by its copper smelters, compared to less than 25 percent in 1985. In 1989, Asarco joined with Montana Resources in the operation of the Butte, Montana copper mine. Asarco also has a large project underway to modernize its El Paso, Texas smelter. Magma Magma is the third largest domestic copper smelter and refiner and fifth largest miner. It had been a subsidiary of Newmont until 1987, when it was spun off. The companys operations are characterized by their physical proximity and technological interaction with one another. All the facilities are located in Arizona. Magma has two mining/milling/ leaching complexes (San Manuel and Pinto Valley), three SX-EW facilities, a smelter and refinery (San Manuel), and one rod plant (San Manuel). In 1989, Magma produced 22 percent of its copper by leaching and SX-EW methods. The company has excess smelting, refining, and rod making capacity. In contrast to Asarco, it is striving to develop its position as a custom smelter. The new flash furnace at San Manuel has a capacity of more than 1 million tpy of concentrates (about 270,000 tpy of blister copper) and is the largest copper smelting furnace in the world. It was scheduled to finish its commissioning period at the end of 1989. In 1989, tolling ~AsNco is also a major lead and zinc producer (see chs. A and 5). 26A5MC0 AIIIIUal Report, 1988.

PAGE 26

20 l Nonferrous Metals: Industry Structure accounted for 27 percent of Magmas refined copper production. In 1989, Magma sold 65 percent of its copper as continuous cast rod, down from 93 percent in 1988. The company is decreasing its rod capacity to focus on producing cathode (primarily for Asian markets). It sold its Chicago rod plant to Cyprus in December 1989. Magma is primarily a copper company, but it produces some molybdenum disulfide, gold, and silver. The companys strategy stresses modernization (e.g., the capital investment in San Manuel) and marketing (e.g., product quality, technical service, and customer relationships). Montana Resources Montana Resources, a smaller copper mining company, operates the historic Continental pit in Butte, Montana. In 1985, Washington Construction purchased the Butte operations from Anaconda Copper (a subsidiary of Arco) intending to salvage them for scrap. After conferring with Anacondas former general manager, however, Washington Construction determined that the mine and mill could reopen profitably. The State and local governments, eager to see the operation contributing to the economy once again, procured credit lines, granted tax cuts, and quickly approved the necessary permits. The company obtained a $0.12/lb reduction in the transportation and refining costs Anaconda had paid to ship the concentrate by rail to California and have it processed in Japan. The local power company granted lower rates for electricity. Finally, the number of workers was cut almost 50 percent, and the top wage was reduced from $22 to $13/hr. As a result, when the East Berkeley Pit reopened early in 1986 as Montana Resources, it was reportedly mining copper for $0.58/lb, compared to Anacondas $0.97/lb. 27 In 1989, Asarco purchased 49.9 percent of a new partnership that owns and operates the Montana copper properties. Copper Range/Metallgesellschaft Metall Mining, a Canadian subsidiary of Metallgesellschaft (MG) bought the Copper Range mine, smelter, and refinery in Michigan in 1989. The high-cost underground operation had at various times in the 1980s been owned by Louisiana Land, Echo Bay, and Northern Copper (an Employee Stock Option Plan). MG (based in Frankfurt, West Germany) is a large metals trading company whose other copper interests are minority holdings in Cominco (Canada) and Norddeutsche Affinerie (West Germany). The Michigan refinery was converted from the fire-refining process to the electrolytic process in the 1982-86 modernization program. Cox Creek Cox Creek began full production at its Baltimore, Maryland refinery and rod mill (formerly owned by Kennecott) in 1988. The company has no mine or smelting capacity. It purchases blister and scrap (for anode production), anode (for cathode production), and cathode (for rod production). Most of the primary feed is imported. Mitsubishi, a partner in the venture, supplies some of the raw material for cathode and rod production. Other partners include Southwire and Halstead Industries. Southwire Southwire operates a refinery in Carrolton, Georgia. It produces copper from both primary and secondary source material. U.S. Interests in Other Countries Several U.S. firms that do not have domestic primary copper facilities are involved in copper projects overseas. Exxon operates the Disputada mine and smelter in Chile. Freeport McMoRan owns 85 percent of the Ertsberg mine in Indonesia. Cerro Copper (part of the Marmon Group) and Newmont have interests in SPCC in Peru. 28 Amoco owns 30 percent of the Ok Tedi mine in Papua New Guinea, USX until recently held equity in Prieska in South Africa. In 1989, the mine closed and USX sold its interest, Chile Chile is the United States strongest competitor in the copper business. It ranks first in mine and smelter production and second in the refining sector. Copper mining began in Chile in the 1850s. After several periods of growth and decline, the country became a consistent producer early in the 20th century. Chile exports 97 percent of its copper production, twothirds in the form of refined copper. Its primary 2TC~eres a Gleam fi he Eye of Copper Producers, Business Week, 1986. 2scemo Copper ~5 a secondary copper smelter in Sauget, n~ois.

Chapter 2-Copper Industry l 21 markets for refined copper are Europe (about 50 percent), Asia (20 percent), and the United States (15 percent). Codelco, owned by the Chilean government, controls about three-quarters of the countrys capacity. It is the worlds largest copper company, operating four major mines (Chuquicamata, El Teniente, El Salvador, and Andina) with a combined capacity of about 1.1 million tpy. 29 Current expansion programs are expected to increase the capacity by 27 percent (300,000 tpy) by the early 1990s. 30 Codelco also has three smelter/refinery complexes (Chuquicamata, Caletones, and Potrerillos). ENAMI, another government-owned company, operates four concentrators, two smelters, and a refinery. The company accounts for about 18 percent of Chiles smelter capacity and 25 percent of its refinery capacity. The ENAMI facilities process concentrates from small and medium-sized independent mines and surplus materials from the Codelco mines. Most private copper production in Chile is run by foreign interests. These companies have been attracted by Chiles moderately rich ores, favorable investment climate, well-developed mining infrastructure, and low paid and highly skilled work force. Exxon operates the Disputada mines and smelter. Anglo American of South Africa has a majority interest in the Mantes Blancos mine, smelter, and refinery. Phelps Dodge runs the small Ojos del Salado copper-gold mine in northern Chile and is exploring the La Candelaria deposit. BHP (Australia), RTZ (U.K.), Mitsubishi and Nippon Mining (Japan), and the World Bank have invested in the La Escondida project. La Escondida the hidden one is slated to come on stream in the early 1990s with a capacity of 320,000 tpy. It is the worlds largest new copper project. Chiles long-term competitiveness is being challenged by declining ore grades. Chilean ore grades, though still higher than average, are falling faster than those elsewhere in the world. The decline is especially pronounced at Chuquicamata where the ore grade was 2.12 percent in 1980, but is projected to fall to l.0 percent by 2000. Codelco has addressed this decline through capacity expansion and exploitation of oxide resources. 31 The strategy has been to expand ore processing capacity enough to keep total refined copper output (and market share) constant or expanding. Central to this plan are the exploitation of oxide reserves from Mina Sur and the Chuquicamata pit, plus the leaching of waste dumps and low-grade sulfide ores. 32 The divestment has been substantial; Codelco has spent $300 to $400 million per year since 1984 for capital improvements and expansions. 33 Japan Japans copper mining industry is very small, but its smelting/refining sector has ranked in the NSW top three since 1970. The industry was built in the 1960s to lessen dependence on foreign supplies and to capture the added value of raw materials processing. Despite having such a large industry, Japan is still a net importer of refined copper. It imports about a quarter of its needs, primarily from Zambia, Chile, and the Philippines. Exports of refined copper are small. To feed its industry, Japan has had to import enormous quantities of concentrates. 34 In fact, to ensure supplies of concentrates, the Japanese supported the development of mines in the Philippines, PNG, Indonesia, and elsewhere. During 1985-88, Japanese smelters imported an average of 3.1 million tonnes of ores and concentrates. The major suppliers were Canada (29 percent), the United States (14 percent), the Philippines, Chile, Papua New Guinea, Indonesia, and Australia.

22 l Nonferrous Metals: Industry Structure mately 60 percent of the copper concentrate traded in 1986 was shipped to Japan. 35 Six firms (Nippon Mining, Onahama, Sumitomo, Mitsubishi, Hibi Kyoda, and Dowa) are engaged in both smelting and refining in Japan. A seventh (Mitsui) is involved in refining only. Given the interests of Mitsubishi and Dowa in Onahama and of Mitsui in Hibi Kyodo, the effective control of Japans smelting capacity is Nippon Mining (26 percent), Mitsubishi (26 percent), Sumitomo (16 percent), Dowa (12 percent), and Mitsui (10 percent). The percentages are similar for the refining sector. Most, but not all, Japanese smelter capacity is located on the coast. This greatly facilitates the delivery of concentrates and the shipping of copper and sulfuric acid to their markets. About 60 percent of the capacity is based on flash furnace technology. Reverberatory furnaces account for most of the rest. In the 1980s, Japan sought new joint projects to counter the tight concentrate markets and production cutbacks by traditional suppliers. These new ventures included projects in Colombia and Chile and equity positions in the United States. Mitsubishi acquired a one-third interest in Chino Mines (including the Chino mine and Hurley smelter and refinery) in 1981. Sumitomo acquired a 15 percent share of the Phelps Dodge Morenci/Metcalf mine in 1985. In addition, Japanese firms are expected to receive much of the copper (in the form of concentrate) from the La Escondida project in Chile when it goes into production. 36 Canada Canada, a medium-sized copper producer, ranks third in NSW mine production and fourth in smelter and refinery production. The countrys mine output is greater than its smelter capacity, so it is a net exporter of concentrates. Canada exports over a third of its concentrate production (primarily to Japan) and over half of its refined production (mostly to the United States and Europe). About three-quarters of Canadas mine production comes from five producers; Highland Valley and BHP-Utah in British Columbia, Falconbridge and Inco in Ontario, and Hudson Bay in Manitoba. Highland Valley (jointly owned by Cominco, Rio Algom, Teck, and Highmont) is the largest. It has no associated smelting and refining capacity, and sells most of its concentrate to Japan. In general, Canadian mines are noted for their large quantities of co-products and byproducts (e.g., nickel, gold, silver, zinc, and molybdenum). About 20 percent of copper mine production comes as a byproduct of the Inco and Falconbridge nickel operations in Ontarios Sudbury district. There are four companies (Noranda, Inco, Falconbridge, and Hudson Bay) involved in Canadas smelting and refining sector. Noranda with its Quebec operations (the Gaspe and Home smelters and the Canadian Copper Refiners division) is the largest. The company has little copper mine capacity, but is a major custom smelter and refiner. In 1989, Noranda and Trelleborg acquired full control of Falconbridge which has mining, as well as smelting and refining, facilities in Canada. With the acquisition, Noranda effectively controls an estimated 55 percent of Canadas smelting capacity and 65 percent of its refinery capacity. Zambia and Zaire The central African copper industry was developed in the 1910s and 1920s by colonial interests. The British operated in Zambia (then Northern Rhodesia) and the Belgians were based in Zaire (then the Belgian Congo). Shortly after Zambia and Zaire gained independence in the 1960s, their industries were nationalized. Both countries export nearly all of their copper. Zambias exports are mostly refined copper and are destined for Europe, Japan, and India. Zaire exported 6 percent of its copper as concentrates, 51 percent as blister (primarily to Belgium), and 43 percent as refined copper (mostly to Europe) in 1985-88. All Zambian copper facilities are run by the state-owned Zambia Consolidated Copper Mines (ZCCM). The major mines are Nchanga, Mufilira, and Nkana. The ores are very rich (averaging 2.0 percent copper). Zambias developed ore reserves are declining quickly and are expected to be depleted by early next century. Large undeveloped reserves exist, however. Recently, Zambia has supplemented ssworld B~eau of Metal Statistics data. 36JOC. wu, ~~e ~er~ ~dus@ of J~p~q &finerazS Year~OO~, vol. ~, 1985 ed.

Chapter 2-Copper Industry l 23 its mine production by toll smelting Zairean concentrates. ZCCM runs three smelters, four refineries, and three electrowinning facilities. Almost a quarter of Zambias refined production comes from leach and electrowinning operations. The state-owned Gecamines operates Zaires principal mines, Dikuluwe/Mashamba, Kov, and Kamoto. The ores average 4.1 percent copper and are the richest copper ores mined in the world. Zaire is less involved in the processing sector than is Zambia. Gec amines does, however, run a smelter and two refineries. The copper industries in Zaire and Zambia share many operating characteristics and problems. They both, for example, produce large amounts of byproduct cobalt. Also, most of their copper output is exported, because the regional market for the metal is small. Transportation is a particularly important factor to these industries. The mines are remote and the transportation network to the distant seaports is cumbersome and unstable. Rail transportation in the region may become more reliable in coming years, because of improving prospects for political stability in southern Africa. However, the investment required to renovate the railroads will be great. Zambia and Zaire also have been plagued with internal political strife, hard currency shortages, power outages, and the acute threat of Acquired Immune Deficiency Syndrome (AIDS). These factors make it difficult to get and keep skilled expatriate personnel and to obtain spare parts for maintenance of the mining equipment. Peru Peru is a medium-sized copper producer which exports 90 percent of its production. During 198588, Peru exported 18 percent of its copper as concentrates (to Japan and West Germany), 28 percent as blister (mostly to Japan and the United Kingdom), and 54 percent as refined copper (to Europe, the United States, and Japan). Peruvian production is dominated by the Southern Peru Copper Corp. (SPCC) open pit mines at Cuajone and Toquepala and smelter at Ilo. SPCC is owned by four U.S. companies-Asarco, Cerro Copper, Phelps Dodge, and Newmont. The venture accounts for about 60 percent of Perus production. There are also numerous smaller operations in Peru, some state-owned and some private, that mine complex silver-copper-lead-zinc ores primarily for the silver. State-owned Centromin runs a smelter and refinery at La Oroya to process its own concentrates as well as those from private mines. Minero Peru, also stated-owned, runs a refinery at Ilo. Perus perennial economic, political, and weather problems make foreign investment there generally risky. Mexico Mexico produces refined copper for domestic uses and exports surplus concentrates. The United States (primarily Magma) is Mexicos largest customer for concentrates. There are two major Mexican copper operations: Mexicana de Cobre and Cananea. Mexicana de Cobre, which is partially owned by U.S.-based Asarco, runs the La Caridad mine and the Nacozari smelter. The company accounts for about 55 percent of Mexicos mine production and 65 percent of its smelter capacity. Cananea, owned by the government, runs a mine and smelter. The company has been slated to be sold under a privatization effort, but efforts in this regard have failed thus far. The privatization is made even more contentious, because the mine is a sensitive national symbol. The mines 1906 strike helped trigger the Mexican Revolution. 37 Cobre de Mexico runs the country's only refinery-the Atzcapotzalco plant in Mexico City. The company has no mines or smelters. Australia Australia exports about a quarter of its concentrate production and almost 40 percent of its refined production. MlMs Mt. Isa complex in Queensland dominates the domestic industry. The complex includes a mine (with very rich ore, 3.3 percent copper) and a smelter. The company also has a refinery at Townsville. The Electrolytic Refining and Smelting Co. of Australia (ER&S) runs a smelter/refinery at Port Kembla. The company is partially owned by RTZ. Australias capacity recently rose with the opening of the 55,000 tpy Olympic Darn (Roxby Downs) project. The operation, which includes amine, smelter, and refinery, is owned by Western Mining and BP. 3TLarry Rohter, Feelings R unning High as Copper Mine Is Shu4 New York Times, Aug. 30, 1989.

24 l Nonferrous Metals: Industry Structure The Philippines The Philippines is a major exporter of copper concentrates. In the early 1980s, nearly all of its copper was exported as ores and concentrates. Now, about half of the production is exported as concentrates (mostly to Japan) and the other half is exported as refined copper. Philippine copper production is dominated by the Atlas mines (Lutopan, Carmen, and Biga). Atlas accounts for about 40 percent of the countrys mine production. Other companies include Maricalum, Marcopper, North Davao, Benguet, and Lepanto. PASAR runs the countrys only smelter and refinery. Papua New Guinea (PNG) PNG began mining copper in the early 1970s. Japan helped finance the PNG mines in order to feed its smelters. All of PNGs production is exported as concentrates. About 40 percent of the concentrates are sent to Japan and 30 percent are sent to West Germany. Two companies produce copper in PNG: Bougainville and Ok Tedi. Bougainvillea, accounted for three-quarters of production in 1988. It was shutdown in May 1989, because of sabotage actions protesting the mines location on ancestral lands. 38 It is not expected to reopen soon, if ever. Ok Tedi began production in 1987. Its capacity is about 600,000 tpy of concentrates, or roughly 200,000 tpy copper. However, the operation been plagued with problems and has yet to operate near its design capacity. Ok Tedi is owned by Amoco (United States), BHP (Australia), several West German fins, and the government of PNG. South Africa South Africa is a smaller copper producer which exports about two-thirds of its production. During 1985-88, the country exported 9 percent of its copper as concentrates, 46 percent as blister, and 44 percent as refined copper to Europe and Japan. The major South African producer is the Palabora operation with its mine, smelter, and refinery in the Transvaal near the Mozambique border. Palabora (partially owned by RTZ) accounts for about 80 percent of South Africas copper production. It also produces uranium and zirconium. Ookiep runs a copper mine and smelter in Cape Province near Namibia. West Germany West Germany is a major copper smelting and refining country, but its mine production is small. It imports nearly all of the concentrates needed to feed the smelting industry. The major sources during 1985-88 were PNG (34 percent), Mexico (19 percent), and Chile (10 percent). West Germany also imports about 55 percent of the refined copper it consumes. The principle sources in 1985-88 were Chile (24 percent), Poland (18 percent), and Zaire (15 percent). The major West German primary copper smelter is run by Norddeutsche Affinerie in Hamburg. The firm is owned by MG, MIM, and Degussa. Belgium Belgium is a major copper refining country but has no mining or primary smelter capacity. It that imports nearly all its blister and anode copper. Over one-half of the blister comes from Zaire (a former colony). South Africa and Sweden accounted for about 11 and 9 percent of imports respectively in 1985-88. Belgiums sole primary copper producer is Metallurgic Hoboken-Overpelt (MHO), a subsidiary of Acec-Union Miniere. It runs the refinery at Olen. Other Countries Other large copper mining companies around the world include: Boliden (Sweden), Freeport Indonesia (Indonesia), Rio Tinto Minera (Spain), and Somincor (Portugal). Other major smelting and refining operations include: Boliden (Sweden), Caraiba Metais (Brazil), BICC (United Kingdom), IMI Refiners (United Kingdom), Korea Mining & Smelting (South Korea), Outokumpu (Finland), and RTB Bor (Yugoslavia). 38$~~ Au&ci~uS Rebel ~ papua New Gfiea shakes Copper Market, wall .$treet JournuZ, Jan. 2, 1990.

Chapter 3 Aluminum Industry INTRODUCTION Alumin um is the newcomer among the metals covered in this study. It was initially isolated as an element in the 1820s and first produced commercially in the 1880s. Uses Alumin um is the most widely used nonferrous metal. Its light weight, corrosion resistance, ease of recycling, and high electrical/thermal conductivity make it useful in a variety of applications. The largest market is the containers and packaging sector (beverage and food cans, foil, etc.). In the United States, this sector accounted for 27 percent of al uminum use in 1988. The other major markets are the transportation sector (21 percent), buildings and construction (18 percent), and electrical uses (9 percent). 1 Production Methods and Technologies Alumin um is the second most abundant metal element (after silicon) in the Earths crust. It can be recovered from many minerals (e.g., clays, anorthosite, nepheline syenite, and alunite), but is produced most economically from bauxite, an impure form of alumina (Al 2 O 3 ). 3 Approximately 90 percent of all bauxite is produced from surface mines. To extract the al uminum, the ore is crushed, washed, and dried (at the minesite) and then refined and smelted. 4 The refining step produces pure alumina from bauxite. The Bayer process, discovered in 1888, is the principal refining method. The bauxite is crushed and ground, then digested in hot (280 to 450 F) caustic soda (NaOH) solution. The alumina minerals in the ore react with the caustic soda and dissolve as sodium-aluminate. Most of the impurities in the ore precipitate out as red mud which is removed by countercurrent recantation and filtration. The solution is then seeded with starter crystals and agitated to crystallize out alumin a hydrate. This material is then calcined in kilns (to remove the water) and the result is pure alumina. The smelting process reduces the alumina to al uminum. Modern processes are based on those discovered independently by Hall and Hroult in 1886. Alumin a is dissolved in a molten cryolite (Na 3 AlF 6 ) bath contained in carbon-lined steel cells (pots). In each pot, a direct current is passed through the bath (between a carbon anode and the carbon bottom of the cell) to reduce the dissolved alumina into aluminum. Molten aluminum collects at the bottom of the pots and is siphoned off into large crucibles. The alumin um (averaging about 99.8 percent purity) is poured directly into molds to produce foundry ingot or further refined/alloyed to make fabricating ingot. Scrap aluminum may be added to the melt either at this last stage or when the ingot is remelted at the foundry or fabricating facility. The smelting process is continuous. Alumina is added, anodes are replaced, and molten aluminum is siphoned off without interrupting current in the cells. A potline may consist of 50 to 200 cells with a total line voltage of up to 1,000 volts at current loads of 50,000 to 225,000 amps. Electricity use in todays smelters is 6 to 8 kWh/lb of aluminum. 5 Electric power is one of the most costly raw materials in al uminum production. lpaticia A.

26 l Nonferrous Metals: Industry Structure THE 1980s The U.S. aluminum market started the 1980s on a good note (see figures 3-1 and 3-2). In 1980, domestic primary al uminum production (4.7 million tomes) was high and prices (averaging $0.76/lb) were high compared with the late1970s. The market went through several cycles during the decade. Prices fluctuated between $0.47 and $0.76/lb in the 1980-87 period, before ending the decade somewhat higher ($1.10/lb in 1988 and $0.89/lb in 1989). U.S. production of primary aluminum also fluctuated, but never rose above its 1980 level. It fell to around 3.3 million tonnes per year (tpy) in 1982-83 and 3.0 million tpy in 1986, and then rose to about 4.0 million tpy in 1988-89. The 1989 output was 13 percent lower than that of 1980, but comparable to the levels of the late1970s. Secondary production (from old and new scrap) rose about 40 percent during the decade. Most of the growth occurred in 1987-89. This category represented about one-third of total U.S. aluminum production during the decade. 6 Us. alumin um consumption also went through several cycles during the decade. Consumption fell from 6.1 million tonnes in 1980 to 5.3 million tonnes in 1982. It then fluctuated between 6.0 to 6.2 million tpy during 1983-86 and 6.4 to 6.7 million tpy during 1987-89. The nonsocialist world (NSW) aluminum market experienced more muted cycles than those that occurred in the United States (see figure 3-3). After the 1982 recession, NSW alumin um production and consumption grew fairly steadily. In 1988, primary production was 13.8 million tonnes (up 8 percent from 1980), secondary production was 5.4 million tonnes (up 40 percent), and consumption was 19.8 million tomes (up 27 percent). The openings, closings, and ownership changes that occurred in the U.S. primary aluminum industry during the 1980s are profiled in table 3-1. The Mount Holly smelter in South Carolina (which opened in 1980) is the most recent alumin um facility to be built in the United States. During the decade, 4 alumina refineries and 10 aluminum smelters closed.

All of the permanently closed refineries and smelters were in the southern United States (Texas, Louisiana, Alabama, Arkansas, and Tennessee). During 1980-88, U.S. refinery capacity declined 29 percent to 5.1 million tonnes of al umina and smelter capacity declined 20 percent to 4.0 million tomes. Amax (through its Alumax subsidiary) became a major aluminum producer during the 1980s. The company grew by building the Mt. Holly smelter and by purchasing Pechineys shares of Intalco and Eastalco in 1983. After consolidating its position, Alumax sold about a quarter of each of its plants to raise money to expand in Canada. Kaiser experienced several ownership changes in the 1980s. The company was acquired first by Alan Clore, a British investor, and then by Maxxam. Three companies (Conalco, Anaconda Aluminum, and Revere Copper and Brass) left the U.S. industry during the 1980s. Another company (Martin Marietta) decreased its presence in the industry by selling one of its smelters and leasing the other to an independent producer. Six companies (Columbia Al uminum, Columbia Falls, Alcan, Vanalco, Ravens~ese figures represent the total al uminum recovered from both new and old scrap. As such they overstate the amount of refined aluminum that is actually entering the manufacturing stream. Old scrap comes from discarded products, new scrap is waste from fabricating and other manufacturing processes.

A seventh (Ormet) was essentially new to the industry also. It was sold to its current owners, Ohio River Associates, in 1986. PRODUCER PROFILES, 1990 Since the second World War, two major groups of countries have been involved in the production of al uminum, the miners and smelters. Bauxite was mined in tropical developing countries such as Guyana, Guinea, Jamaica, and Suriname. Aluminum was smelted in the electricity-rich developed regions of North America and Europe. Alumin a refining, the middle processing step, originally took place in the smelting countries, but is now done in the mining countries also. A new group of integrated producing countries, active in all three sectors of the primary al uminum business, has emerged in the last 20 years. Australia and Brazil are two such producers (see figure 3-4). Australia is the largest NSW bauxite miner and alumin a refiner, and ranks third in smelting. Brazils industry is smaller, ranking third in mining, fifth in refining, and fourth in smelting. The other major bauxite producers are involved in the processing sector to varying degrees. Guinea, Guyana, and Sierra Leone have little or no refining capacity and export most of their output. Jamaica, Suriname, India, Yugoslavia, and Greece have Figure 3-3NSW Aluminum Production and Consumption, 1975-88 Millions of tonnes 25 20 / 15 10 5 0 75-79 80 81 82 83 84 85 86 87 88 Year ~ Primary production ~] Secondary production Consumptio n NOTE: Secondary production is refined metal and other products recovered from old and new scrap.

Until the ascendancy of Australia and Brazil, the smelting industry was located almost exclusively in North America, Japan, and Europe. The United States has been the largest smelting country since the birth of the industry. Japan was the second largest smelter in the mid1970s, but has since closed most of its capacity because of high electricity prices. Canada is now the second largest producer. In Europe, where most nations have some smelting capacity, Norway and West Germany are the industry leaders. Among the older smelting countries, the United States, West Germany, and Canada have the largest refining sectors. Despite the industrys geographical diversity, a high degree of concentration and vertical integration was attained by the major companies. The Big Six (Alcoa, Alcoa, Kaiser, Reynolds, Pechiney, and Alusuisse) operated as an oligopoly for most of the post World War II period (see box 3-A). Although these companies were principally smelters and fabricators, they owned or controlled most of the worlds bauxite production. Over the years, the Big Six have lost some of their influence over the industry, especially in the mining sector, but the individual companies remain important. The International Bauxite Association (IBA) was established in 1974. Its members are Australia, Ghana, Guinea, Guyana, India, Indonesia, Jamaica,

These countries produced about 85 percent of the NSWs bauxite and about half of the alumin a in 1988. The goals of the IBA are to promote the orderly and rational development of the bauxite industry, to secure fair and reasonable returns for the exploitation of the bauxite, and to generally safeguard members interests in relation to the bauxite industry. 7 The interest in establishing the organization came in the early 1970s. Bauxite-producing nations were dissatisfied with the revenues their resources were generating. It was also during this period that bauxite levies and government equity positions in bauxite companies became popular. The final inducement for formin g a producer organization came when the Organization of Petroleum Exporting Countries (OPEC) was successful in quadrupling oil prices in 1973. 7G.R. p~t~rSO~ and S.J. ~belbid~, A/uminumAvailabi/i@arkel Economy Coun&ies, IC 8917 ~~~gto~ m: U.S. Department of the rnteriOr, Bureau of Mines, 1983).

30 l Nonferrous Metals: Industry Structure Box 3-AThe Big Six Aluminum Companies Aluminum was not produced commercially until late in the 19th century, long after most other structural metals had found widespread use. Alcoa (then the Pittsburgh Reduction Co.) controlled the North American aluminum industry from its inception until World War II. In the mid-1940s, the countrys capacity was tripled to meet growing military needs. The U.S. Government, through the Defense Plant Corp., built new aluminum smelters which were then operated by Alcoa and several other companies. Following the war, the smelters were leased and then sold to two of the operators, Kaiser and Reynolds as part of an antitrust action against Alcoa. In 1950, Alcoa was ordered to divest itself of its Canadian affiliate Alcan (then Aluminum Ltd.). Consequently, the North American monopoly held by Alcoa was replaced by the oligopoly resulting from the emergence of Alcan, Kaiser, and Reynolds as major producers. In Europe, a more oligopolistic aluminum industry developed in the early years. After World War II, government actions consolidated the position of Pechiney and Alusuisse in this market. Though their market control declined, these Big Six companies accounted for about 65 to 85 percent of NSW aluminum production from World War II to the early 1970s. The leaders were able to set prices at cost plus a margin of profits, know as producer prices. Prices remained stable, because changes in demand were met with immediate adjustments to inventories and operating rates. In the long run, the major producers kept prices stable by building capacity in anticipation of demand. This planned excess capacity enabled the major producers to supply their customers as their demand increased and also provided an added barrier to entry into the industry. l The high rate of growth in aluminum consumption and the coordination of capacity expansion among the major producers made this strategy very successful. During this time, the major producers strove for a high degree of vertical integration. Control of bauxite and alumina resources enabled them to supply their own operations at cost, with profits realized at the latter stages of production. Excess raw materials were selectively sold by the leaders so that they could decide, in effect, who their competition would be. The same factors that strengthened Alcoas earlier in the century-control of natural resources, high barriers to entry and access to the lowest cost energyprovided the oligopolistic leaders with the competitive edge to control the industry from the 1940s until the 1970s. In the early 1970s, the aluminum industry changed radically and the competitiveness of the top producers was shaken. Electricity, labor, and capital costs rose sharply and demand slowed. As the profit margins declined, the major producers began to pursue different strategies. LME pricing took effect in the late 1970s. The leaders no longer operated as a cohesive group. Some sought to maintain prices by reducing production, while others built capacity in low cost foreign locations. Both strategies were unsuccessful at maintaining the producers market power.

Chapter 3--Aluminum Industry l 31 United States The United States mines little metallurgical-grade bauxite, but is the NSWs second largest alumina refiner and largest aluminum smelter. All of the domestic alumin a refineries are located near the Gulf Coast (see table 3-l). Smelter capacity is located roughly one-third in the Pacific Northwest, one-third in the Ohio Valley, and the rest in the Carolinas, New York, and Texas. Nearly all U.S. aluminum production is based on imported raw material. In terms of recoverable aluminum, the imports are about one-half bauxite and one-half alumin a The principal sources are Guinea and Jamaica for bauxite and Australia for alumina. 8 The major U.S. aluminum companies own shares of many of their foreign suppliers. 9 The United States produces about a quarter of the NSWs alumin um metal, but does not make enough to meet its fabricating needs. During 1984-88, the countrys net imports averaged 12 percent of its consumption of primary and secondary aluminum. Most of the imported metal comes from Canada. Exports during this period were 17 percent of domestic production. Three companies (Alcoa, Reynolds, and Kaiser) own about 90 percent of the countrys refinery capacity (see figure 3-5). They, along with a fourth firm (Alumax), own about 60 percent of domestic smelter capacity. These companies are also heavily involved in the downstream fabrication sectors of the business. Having both smelting and fabricating capabilities helps the companies manage business risk. Though the various downstream products vary in their exposure to alumin um ingot prices, rising prices generally favor smelters and declining prices favor the fabricated products. 10 The remainder of the primary aluminum industry is comprised of seven domestic firms (Ormet, Southwire, Columbia Aluminum, Columbia Falls, Vanalco, Ravenswood, and Northwest Alumin um) and two Canadian firms (Alcan and Noranda). Alcoa Early in the century, Alcoa held a monopoly over the alumin um industry. Though its influence has since dimini shed greatly, it remains the worlds largest aluminum company and the Nations leading nonferrous metals producer. 11 Its domestic facilities include refineries in Texas and Arkansas, and smelters in Texas, Indiana, Washington, Tennessee, New York, and North Carolina. The six smelters account for about 31 percent of total U.S. capacity, and an estimated 60 percent of the companys worldwide smelting capacity. Alcoas major foreign interests include bauxite and alumina facilities in Jamaica, Suriname, and Guinea; and smelters in Australia, Brazil, Norway, Suriname, and Mexico. Alcoa has diversified over the years, but is still principally an aluminum company .12 Aluminum ingots, chemicals, and fabricated products account for about 90 percent of the companys sales. Some of the alumin um is sold as primary metal, but more is sold as packaging materials (e.g., can stock and bottle caps) and sheet, plate, and extrusions for aerospace and industrial applications. The companys emphasis on the fabricating business has left it with insufficient primary metal capacity to meet all of its needs. Alcoa buys about one-half of the aluminum used in its fabricated products. To further its goals as both a buyer and a seller of aluminum ingot, the company is an active hedger in the commodities futures markets. Alcoa has a reputation for being among the most innovative of the companies in the nonferrous metals industry. It spends heavily on research and ?IXuing 1985-88, bauxite imports came from Guinea (50 percent), Jamaica (23 percent), Australia (11 percent), and Brazil (5 percent). Alumina imports came horn Australia (80 percent), S uriname (8 percent), and Jamaica (5 percent). U.S. Bureau of Mines, Mineral Commodity Summa ries, 1990 ed.

It sought to withdraw from the primary al uminum business, to develop a higher degree of downstream integration, and to diversify into the production of engineering materials. The goal was to have one-half of its sales come from new nonaluminum businesses by 1995. The company has since slowed its diversification into engineering materials and concentrated its efforts on the aluminum metal and fabrication businesses. 14 Reynolds, the second largest U.S. aluminum company, has been in production since the 1940s. It operates a refinery in Texas and smelters in Washington, New York, and Oregon. The three domestic smelters account for 11 percent of U.S. capacity. Reynolds major foreign operations include bauxite mines in Brazil, Jamaica, Guinea, and Australia; refineries in Australia, Jamaica, and West Germany; and smelters in Canada, Ghana, Venezuela, and West Germany. At yearend 1988, over 90 percent of the companys primary capacity was in North America. Alumin um products accounted for about 85 percent of the companys sales in 1988. Reynolds sells some alumin um ingot, but stresses its fabricating business. The companys emphasis on finished goods, however, is greater than that of its competitors. It is the only aluminum producer that makes cans from its can stock. Reynolds largest business is its packaging and containers line, which includes al uminum, plastic, and paper consumer products (e.g., aluminum foil, plastic wrap, waxed paper, food containers, and garbage bags). The company also manufactures aircraft and automotive products.

Since 1986, the company has been investing heavily in precious metals. It has acquired interests in two Australian gold mines (Boddington and Mt. Gibson). In 1988, Reynolds share of the gold from these two mines was 4.4 million grams. Though Reynolds stresses that its emphasis remains with fabricated and finished products, it is investing in additional alumin um ingot capacity. It is expanding its Baie Comeau smelter in Canada from the present capacity of 280,000 tpy to 400,000 tpy by 1992. Also, Reynolds acquired a 25 percent equity position in the Becancour smelter in Canada in 1987. The smelter is currently being expanded by 50 percent to 360,000 tpy. 15 The company claims that its present sources of bauxite and alumina (including joint ventures and long-term supply contracts) are more than adequate to meet its requirements for the foreseeable future. Reynolds is a net buyer of scrap and ingot. Capital spending for modernization in the rnid1980s was primarily to lower basic metals costs (reduced by about 25 percent during 1983-87). The companys emphasis is now on improving fabricating costs and expects to spend about $300 million per year during 1988-93 in this effort. Its research and development budget has been $32 million annually during the mid-1980s. The emphasis is on the development of products, such as the resealable aluminum cans. Alumax Amax, through its Alumax subsidiary, is the third largest U.S. alumin um producer. It operates three smelters, located in Washington, South Carolina, and Maryland. The company owns 11 percent of U.S. smelter capacity. 16 It also has a one-quarter share in the Becancour smelter in Canada. Amax is a century-old minerals company that has been involved in the aluminum industry (mostly as a partial owner of Alumax) for 35 years. 17 Alumax only became a major producer in the 1980s. It expanded by building the Mt. Holly, South Carolina smelter in 1980 and purchasing the U.S. assets of Pechiney (Howmet) in 1983. In 1986, Amax acquired full control of Alumax. During 1987-88, Amax sold 27 percent of the Mt. Holly smelter to Clarendon Ltd. and one-quarter of its Washington (Intalco) and Maryland (Eastalco) smelters to the Mitsui trading company and two Japanese fabricating companies. 18 Alumax has a 10-year tolling contract with Clarendon Ltd. The agreement covers 50 percent of Mt. Hollys production, but reports are that Clarendon Ltd. has been taking about three-quarters of the smelters output. 19 Amax has stated that it intends to rebuild its primary metal business and be more involved in the sale of al uminum metal. 20 To this end, the funds from the two equity sales were used to obtain the companys interest in the Becancour facility in 1988. Alumax also has plans to build a 200,000 tpy smelter at Deschamault in Quebec. Amax produces alumin um, coal, molybdenum, and gold. 21 Aluminum accounted for about twothirds of the companys sales during 1987-88.

The company is especially strong in the architectural and building products line. Kaiser Kaiser, the fourth largest domestic producer, is the smallest of the U.S. majors. The company has been producing aluminum since the 1940s. Its domestic operations include a refinery in Louisiana and two smelters in Washington. The smelters account for 7 percent of U.S. capacity. Kaisers foreign interests include bauxite mines in Jamaica; alumina refineries in Jamaica and Australia; and smelters in Ghana, the United Kingdom, Australia, and Bahrain. Kaiser was the target of several corporate takeover attempts during 1985-87. British investor Alan Clore was successful in acquiring the company in 1987. However, he overextended himself in the process and was forced to sell out to Maxxam in 1988. Maxxam has refocused the companys businesses and reduced its debt by restructuring and asset selling. Kaiser is being regrouped around the al uminum metal products business. Since 1984, the company has sold its agricultural, industrial, and specialty chemicals, refractories, international trading, and real estate operations. The companys Ravenswood smelter was sold to the Stanwich Partners in 1988. Further sales, particularly of foreign operations, are expected. 22 Kaiser fabricates most of the aluminum it produces. In 1987, the company sold 83 percent of its al uminum in the fabricated form. The biggest product groups are can stock and other sheet and plate products. Other lines include rod, bar, wire, forgings, and extrusions. Alcan Alcan is Canadas principal aluminum company, and most of its operations are in that country (see next section). In the United States, it owns the Sebree, Kentucky smelter, which it bought from Atlantic Richfield (Arco) in 1984. Noranda Noranda is a diversified minerals producer that is based in Canada. Its principal primary aluminum facility is its New Madrid, Missouri smelter. 23 Norandas aluminum fabricating plants are all located in the United States. Overall Norandas al uminum operations contributed 9 percent of the corporations operating profit (revenues minus costs and depreciation) in 1988. 24 Other U.S. Producers Independent firms held 27 percent of U.S. smelter capacity in 1988. National-Southwire ran the smelter at Hawesville, Kentucky. The company, a joint venture of National Intergroup and Southwire, had operated the plant since the late 1950s. In early 1990, Southwire bought out National Intergroup and became sole owner of the smelter. The other six independent companies are all new to the aluminum industry in the 1980s. Ormet, the largest, has a refinery in Louisiana and a smelter in Ohio. Ohio River Associates, an investor group, bought the company from Conalco (Consolidated Aluminum, a subsidiary of Alusuisse) and Revere Copper&Brass in a leveraged buyout in 1986. The purchase agreement calls for the two previous owners to receive part of Ormet product for 4 years. Montana Alumin um Investors purchased the Columbia Falls, Montana smelter from Arco in 1985.

Chapter 3--Aluminum Industry l 35 num (Norway) and BHP (Australia). Columbia Alumin um bought the Goldendale, Washington smelter from Commonwealth Alumin um (a subsidiary of Comalco) in 1987. It tolls for Hydro Aluminum and Reynolds, and also produces metal for its own account. Vanalco (owned by Bay Resources) purchased the Vancouver, Washington smelter from Alcoa in 1987. The company produces metal for its own account. Its alumin a comes from Alcoa of Australia. Northwest Aluminum (an investor group headed by a former Bonneville Power Authority executive) negotiated a lease-buy arrangement for The Dalles, Oregon smelter with Martin Marietta in 1986. Northwest Alumin um is operating the smelter under a 3to 5-year lease, and has the option to purchase the plant when the lease expires. The plant is tolling alumina for Clarendon Ltd. Ravenswood (owned by Stanwich Partners) purchased its West Virginia smelter from Kaiser in 1988. Canada Canada ranks second in the smelting sector of the NSW aluminum industry. It is a much smaller refining country and has no mine capacity. The industry is based in Quebec, and to a lesser extent, British Columbia. The major foreign sources of alumin a are Jamaica and Australia. Canada exports about three-quarters of its primary aluminum. During 1984-88, the United States received 75 percent of Canadas alumin um exports. Alcan dominates the Canadian aluminum industry. It runs the countrys sole alumina refinery, the Vandereuil plant in Jonquiere, Quebec. The facility supplies an estimated 30 percent of Canadas al umina needs. Its bauxite feed is imported from Brazil (mostly MRNs Trombetas mine), Guyana, and Guinea. Alcan has six Canadian smelters, five in Quebec and one in British Columbia, which account for 68 percent of the countrys capacity. The largest smelter is the Arvida operation attached to the Vandereuil refinery. Alcans foreign interests include bauxite mines in Brazil, Guinea, Ghana, Jamaica, India, and Malaysia; refineries in Australia, Brazil, Guinea, Jamaica, India, Ireland, the United Kingdom, and Japan; and smelters in Australia, the United States, Brazil, India, the United Kingdom, Japan, and Spain.

A new smelter is being built at Laterriere, Quebec to replace several potlines of similar capacity at the Arvida plant that are to be closed for environmental reasons. Facilities are being upgraded to produce higher value ingots. The companys Kemano hydroelectric plant in British Columbia is being expanded to power new smelters that will be built when market conditions are right. Alcan is also investing in new businesses such as metal matrix composites, alumin um lithium alloys, fiber optics, ceramics, and micro separation technologies. The company has adopted a conservative approach to get into these new businesses. It is building each business step-by-step through joint research projects, small acquisitions, and strategic alliances. There are two Canadian smelters that are not affiliated with Alcan. Both are in Quebec. The larger, and older, is the Baie Comeau operation owned by Reynolds. It currently accounts for 19 percent of the countrys capacity, and is being expanded by 120,000 tpy. The other is the Becancour smelter, equally owned by Reynolds, Pechiney, Alumax, and Albecour (an arm of the Quebec Government).

36 l Nonferrous Metals: Industry Structure has announced that it will build a new 278,000 tpy smelter at Sept-Iles, Quebec. Alumax has plans to build a 200,000 tpy smelter at Deschamault in Quebec. When the expansion projects and the new smelters have all been completed (probably in 1992), Canada will overtake the United States as the worlds largest alumin um producer. Australia Australia is the NSWs largest bauxite miner and al umina refiner, and ranks third in aluminum smelting. It exports an estimated 95 percent of the al uminum content of its bauxite output. Of these exports, roughly one-quarter is in the form of bauxite, 60 percent is in the form of alumin a, and the remainder is aluminum metal. Over half of the primary metal exports are bound for Japan, and most of the remainder go to other Asian countries. Australias alumin um industry is comprised of five groups of companies, Alcoa of Australia, Comalco, Gove, Worsley, and Alcan Australia. Each is affiliated with the major multinationals. Alcoa of Australia (partially owned by Alcoa and Western Mining) is Australias largest bauxite producing concern. It has three large mines (Jarrahdale, Huntley-Del Park, and Willowdale) and three alumin a refineries in the Darling Range of Western Australia. It is the worlds largest alumina seller. The company also operates two smelters, both near Melbourne in Victoria. It owns the Point Henry facility, and has a 45 percent interest in the Portland plant. 27 Comalco (partially owned by CRA, an RTZ affiliate) is the countrys second largest producer. The company operates two mines (Weipa-Andoom and Mitchell Plateau) in northern Australia. Bauxite from the Weipa-Andoom mine is refined by Queensland Alumin a or exported to Japan or Europe. Queensland Alumin a (owned by Comalco, Kaiser, Alcan, and Pechiney) runs the Gladstone refinery on the east coast of Queensland. Two smelters, Boyne and Bell Bay, receive their alumina feed from Gladstone. Boyne (owned by Comalco, Kaiser, and a Japanese consortium) is located next to Queensland Alumin a. Bell Bay (owned by Comalco) is located in Tasmania. Gove (partially owned by CSR) is the common thread in the Gove Project mine and refinery and the Tomago smelter. The Gove Project (owned by Gove and Alusuisse) in the Northern Territories is managed by Nabalco. Bauxite from the mine is either refined on site or exported. Tomago (partially owned by Gove, Pechiney, and VAW) runs a smelter in New South Wales. Australias other producers are Worsley and Alcan Australia. Worsley (owned by Reynolds, Billiton/Shell Australia, and Kobe Alumina ) runs the Mt. Saddleback mine and the Worsley refinery in the Darling Range of Western Australia. Alcan Australia runs the Kurri Kurri smelter in New South Wales. Brazil Brazil ranks third in the NSW in bauxite mining and fourth in aluminum smelting. The refining sector is disproportionately small, thus Brazil has net exports of bauxite and alumin um, but net imports of alumin a. The bauxite is exported mostly to Canada and Venezuela. During 1984-87, Brazil exported 41 percent of its primary alumin um output, primarily to Japan, Europe, and the United States. Mineracao Rio do Norte (MRN) is Brazils largest bauxite mining company. The companys largest holder is the partially government-owned Companhia Vale do Rio Doce (CVRD). Lesser stakes in MRN are held by Alcan, Cia Brasileira de Aluminio (CBA), Billiton, Reynolds, and Norsk Hydro. MRNs mine at Trombetas in the State of Para accounts for about three-quarters of Brazils bauxite production. Most of the operations output is exported. Brazils other mines are run by Alcan Al uminio, CBA, and Alcoa Al uminio (partially owned by Alcoa). Their bauxite is, for the most part, refined and smelted domestically. Four companies operate both refineries and smelters in Brazil. The largest is Alumar (owned by Alcoa Alumini o and Billiton). Its facilities are located at Sao Luis, Maranhao and currently account for about 28 percent of the countrys smelting capacity. The Sao Luis smelter is being expanded from 245,000 tpy to 328,000 tpy. The other refinery/smelter complexes are run by CBA (Sorocaba, Sao Paulo), Alcan Aluminio (Minas Gerais operations), and Alcoa Alumini o (Pocos de Caldas, Minas Gerais). 27~cOa (~ough Al~~~ of Au~tr~a) Oms 51 percent of the po~t Heq smelter, but has acwss to all of the metal produced.

Chapter 3--Aluminum Industry l 37 Two companies, Albras and Valesul, are involved only in the smelting sector. Albras (owned by CVRD and a Japanese consortium) runs a smelter at Belem, Para. A project to double the capacity of the Belem smelter is underway. Albras has been dependent on imported alumina because finding problems stalled the construction of the nearby Alunorte refinery. The refinery should be in production by the end of 1990. Valesul (owned by CVRD, Billiton, and Reynolds) runs a smelter in Rio de Janeiro. Jamaica Jamaica is the fourth largest NSW miner and refiner, but has no smelting capacity. Most of the countrys operations are partnerships between the government and foreign fins. The largest bauxite producer is Kaiser Jamaica (owned by the government and Kaiser). Its Water Valley mine has no associated refinery in Jamaica; most of its bauxite is sent to Kaisers Gramercy, Louisiana plant. Three other companies operate both mines and refineries in Jamaica. Alpart (owned by Kaiser and Hydro Alumin um) has facilities at Nain. Clarendon Alumina (owned by Alcoa and the government) runs the Breadnut Valley mine and the Clarendon refinery. Jamaican (owned by Alcan and the government) has operations at Ewarton and Kirkvine. Jamaicas alumin a production was uneven in the mid1980s. The government and the companies disagreed on whether or not to close various facilities. Alumina export levies and sagging alumina markets (especially the closures of U.S. Gulf Coast smelters) were at the center of the disputes. These problems have generally been resolved. Significant expansion projects are being considered by Alcan, Alpart, and Comalco. Guinea Guinea, which ranks second in NSW bauxite output, is the worlds largest bauxite exporting country. It has little refinery capacity and no smelting capacity. The Sangaredi-Boke mine is Guineas largest mine, accounting for about two-thirds of the countrys capacity. It is run by Compagnie des Bauxites de Guinea (CBG) which is owned by the government and Halco (a consortium of Alcoa, Alcan, Pechiney, VAW, Comalco, Aluminia SpA, Reynolds, and Billiton). Most of the bauxite is shipped under long-term contracts to refineries in Europe and the United States. The Endasa plant in Spain and Aughinish plant in Ireland are major recipients. 28 The next largest mine, Debele, is run by the state-owned Offices de Bauxites de Kindia (OBK). The Soviet Union helped finance the mine and takes a large portion of its output under a barter arrangement. The remainin g mine, and the sole refinery, are run by Friguia. The company is owned by the government and Frialco (a consortium of Noranda, Pechiney, British Alcan, Alusuisse, and VAW). India India is currently a medium-sized bauxite miner and alumin a refiner. It will become a comparable al uminum smelter when ongoing expansion projects are completed in the early 1990s. There are four integrated companies producing aluninum in India. Nalco and Bharat are both owned by the government. Indalco is partially owned by Alcan. Hindalco, until recently, was partially owned by Kaiser. A fifth, smaller company, Malco operates a refinery and smelter, but has no mines. Suriname Suriname, once the third largest bauxite miner, is a medium-sized bauxite producer with a small amount of refining and smelting capacity. Suralco (owned by Alcoa) and Billiton operate facilities in the country. Suralco runs a mine and a smelter. Suralco and Billiton jointly own another mine and a refinery. Yugoslavia Energoinvest (owned by the government) is Yugoslavias largest alumin um producer. It runs four mines, two refineries, and a smelter. About half of its alumin a production is smelted domestically, and half is exported, primarily to the Soviet Union. The government also owns the countrys three other smelters. Greece Greece exports most of its bauxite. Parnasse, the countrys largest bauxite producer, accounts for over half of the countrys output. The company exports about 60 percent of its bauxite primarily to the ~AnnW[ Re~ie~ of the Wor[d Alu~num I&usmes 1985, Shemon Lehman Brothers.

38 l Nonferrous Metals: Industry Structure Eastern bloc and Europe. Greek Helikon, another bauxite producer, also exports much of its product. Elbaumin (owned by the government) sends its bauxite to the countrys only refinery and smelter, run by Aluminium de Grece (partially owned by Pechiney). Hellenic Alumin a (ELVA) is constructing an alumina plant at Thisbi. The plant, which is being partially funded by the Soviet Union, is scheduled for completion in 1992. All of the refinerys output will be exported to the Soviet Union. Guyana Guyana has three mines and is estimated to produce 60 percent of the worlds nonmetallurgical grade bauxite. It exports most of its product. Guyana nationalized its industry in 1971. Sierra Leone Sierre Leone Ore and Metals (SIEROMCO), owned by Alusuisse, is the countrys the sole producer. It exports all of its bauxite, primarily to Europe. Venezuela Venezuela has carved out a niche as an alumina refiner. It imports bauxite and exports alumin a. The country currently has ambitious plans to expand its capacity in the smelting sector. The industry is dominated by the state-owned Corporation Venezolana de Guayana (CVG). The company has some stake in all of the country aluminum operations. Venezuela began bauxite production with the opening of the Bauxiven (owned by CVG and Alusuisse) Los Pijiguaos mine in 1987. The mine is expected to produce 4 million tpy of bauxite at full capacity. At this rate, Venezuela would be the fifth largest bauxite producer. Inter-alumina (owned by CVG and Alusuisse) runs the countrys sole refinery. It is located at Ciudad Guayana next to two smelters. The larger smelter is run by Venalum (owned by CVG and a consortium of six Japanese companies). The other is operated by Alcasa (owned by CVG and Reynolds). Venezuela is undergoing an aggressive expansion program to take advantage of its vast bauxite resources and its position as the worlds lowest cost aluminum producing country. The Interalumin a refinery is being enlarged. The Venalum and Alcasa smelters, with a current capacity of 600,000 tpy, are to be expanded to about 860,000 tpy in the early 1990s. Furthermore, seven other CVG-associated companies Alisa, Alamsa, Aluguay, Alusur, Aluyana, Vexxal, and Angostura have construction plans. 29 If all of the plans were realized, Venezuelas capacity would rise to 1.4 million tpy by 1994 (2.0 million tpy by 2000) and the country would be among the top three or four NSW aluminum smelters. 30 However, the construction schedules are far from certain. The government has proposed delaying five of the seven planned smelters, because of financial problems. Only Alisa has arranged the financing necessary to begin construction on its 120,000 tpy facility. Norway Norway produces no bauxite or alumin a, but is the worlds fifth largest alumin um smelter. It exports about 90 percent of its production, primarily to West Germany, the Netherlands, Italy, and the United Kingdom. Norways industry is comprised of three fins. Hydro Alumin um (owned by Norsk Hydro) is the largest. It has four smelters and accounts for almost three-quarters of Norways capacity. Hydro Aluminum has tolling agreements with Columbia Falls and Columbia Aluminum in the United States, and owns a share of Alpart in Jamaica, to enhance its geographical diversification. 31 Norways other producers are Mosal (owned by Alcoa and Elkem) with two smelters and Soral (owned by Norsk Hydro and Alusuisse) with one smelter. West Germany After Norway, the largest of the European producers is West Germany. Its refinery production is handled by three fins, Alumin ium Oxide Stade, Alusuisse, and VAW. Alumin ium Oxide Stade (owned by Reynolds and VAW accounts for almost zg~ong CVG.S partne~ in fiese ventures are Austria Metall and Pechiney for Alams~ and Alcoa and Sural for Ah.lsm, possibly ~usuisse and Alumax for Aluguay.

Chapter 3--Aluminum Industry l 39 60 percent of the countrys refinery capacity. The major suppliers of concentrates are Australia, Guinea, and Sierra Leone. Four films are involved in the smelting sector. VAW owns about half of the capacity and Alusuisse, through two subsidiaries, accounts for a quarter. The others are Hamburg Alumin um (owned by Reynolds, VAW, and the City of Hamburg) and Hoogovens. Imports of alumin a come primarily from Australia, Italy, and Guinea. France Frances sole alumin um producer is Pechiney (owned by the government). The company is the largest aluminum producer in Europe and the fourth largest in the world. It has interests in bauxite mines in France, Guinea, and Greece; refineries in France, Guinea, Greece, and Australia; and smelters in France, Greece, the Netherlands, Australia, and Canada. Pechiney has a 30 percent interest in the 180,000 tpy Alamsa smelter being proposed in Venezuela. It announced in 1988 that it would build a new 210,000 tpy state-of-the-art smelter in Dunkerque, France. It recently purchased American National Can to enhance its fabricating capabilities in the United States. Switzerland Switzerland produces little aluminum, but is home to Alusuisse. The company (also called Swiss Alumin um) is the smallest of the majors. It owns major shares of bauxite mines in Australia, Sierra Leone, and Guinea; refineries in Australia and West Germany; and smelters in Norway and West Germany. Minor interests are held in mines and refineries in Venezuela. In 1987, 69 percent of Alusuisses sales came from aluminum products and the remainder came from chemicals. The aluminum was sold mostly as fabricated products (64 percent), but also as primary metal (20 percent), and bauxite and alumina (1 0 percent). The major markets were Europe and, to a lesser extent, North America. Because of the weak European markets of the mid-1980s, the company retreated from raw material production and expanded into fabricated products. Alusuisses corporate strategy calls for a partial withdrawal from primary metal to concentrate on specialized, high-value aluminum products an d ceramics, composites, and chemicals. The companys primary metal capacity has been pared to less than half of the 800,000 tpy it once was. About 30 to 40 percent of the metal required by the fabricating operations must be brought from outside the corporation. The smelter capacity that remains is relatively high cost. The alumina and fabricated products segments are somewhat healthier. 32 The Middle East There are several producers in the Middle East taking advantage of the low-cost energy (based on natural gas) in that region. The current producers are Alba (partially owned by Reynolds) in Bahrain and Dubai Al uminum in the United Arab Emirates. Capacity in the region is currently being expanded considerably. Alba is expanding its smelter from 180,000 tpy to 225,000 tpy in a program to be completed in 1990. The Bahrain Government is considering further expanding the plant to 400,000 tpy. A consortium of Chinese, U. S., and British investors have plans to build a 240,000 tpy smelter in Qatar, UAE to be completed in 1992. Alujain (controlled by Saudi shareholders) has talked of building a 220,000 tpy smelter in Saudi Arabia. 33 Other Countries Other producers include: Alumin io Espanol and Endasa in Spain; British Alcan and Anglesey Alumin um in the United Kingdom; Hoogovens in the Netherlands; Alumin ia SpA in Italy; Austria Metall and Salzburger (Alusuisse) in Austria; Grange Aluminum in Sweden; and Aughinish (owned by Alcan and Billiton) in Ireland. szpa~o de Sk From Oligopoly to Competition: The Changing Aluminum Industry, Centre dfionomie des Resources Naturelles (CERNA), Mole Nationale Sup&ieure des Mines des Paris, February 1989. ssDavjd Humphreys, ~ umimq Mining Journal, Mining Annual Review, 1989.

Chapter 4 Lead Industry INTRODUCTION Lead, one of the oldest known metals, has been used since 3000 BC. In the 20th century, the development of froth flotation techniques reduced production costs dramatically and made previously uneconomic deposits viable. The use of lead increased greatly with invention of the electric starting system (which required storage batteries) for automobiles. Batteries States, lead percent of Uses are leads largest market. In the United acid storage batteries accounted for 78 domestic lead consumption in 1988. These batteries are used for auto ignition starters, uninterruptible power supplies (for computer systems at hospitals, banks, and communications networks), and standby power supplies (for emergency lighting and telephone systems). Other major uses include paints, glasses, and ceramics additives (5 percent of domestic consumption), ammunition (4 percent), solder (2 percent), building products, pipes, traps, and cable coverings. 1 Leads use as a gasoline additive declined greatly in the last two decades because of environmental regulations. 2 This, and other, decreases in leads dissipative uses has made the metal more recyclable and increased the importance of the secondary market. Production Methods and Technologies Lead is produced from galena (PbS), and less commonly, cerussite (PbCO 3 ) and anglesite (pbSO 4 ). Commercial ores contain 4 to 12 percent lead. Galena often contains silver/gold and is associated with sphalerite (ZnS), pyrite (FeS 2 ), and chalcopyrite (CuFeS 2 ). Thus, byproduct and coproduct recovery are frequently important aspects of lead production. Over 80 percent of nonsocialist world (NSW) lead mines are underground operations. After mining, the ores are beneficiated (at the minesite) to raise the lead content and to remove most of the associated zinc, iron, and waste rock. Any copper, silver, and gold, in the ore normally remain with the lead and are recovered at the smelter or refinery. A variety of separation processes are used to concentrate lead ores, but froth flotation is generally used for sulfide ores such as galena. The resulting concentrate contains about 70 percent lead. At the smelter, the lead concentrates are pelletized and sintered to remove most of the sulfur. The lead oxide sinter product is then charged (along with coke, fluxes, and dross) into the top of the blast furnace or the Imperial smelting furnace. 4 As the feed descends through the furnace, the burning coke melts the charge and forms a gas which reduces the lead oxide to metallic lead. The lead, called bullion, and the slag are tapped from the bottom of the furnace. The process is continuous. The slag carries out most of the zinc, iron, silica, lime, and other gangue. The bullion, which contains silver, gold, and copper, is transferred to dressing kettles. As the bullion cools, most of the copper becomes insoluble and separates out into the dross which is skimmed off. 5 The decopperized bullion is then sent to the refinery. Most lead bullion is refried by pyrometallurgical methods. 6 This involves a series of processes that remove the antimony (softening), silver (Parkes process), zinc (vacuum dezincing), and, if need be, IWillim D.

It is basically a conventioti b~t furnace with a zinc recovery section added, It can produce both lead and zinc from a variety of mixed, low-grade, and oxide concentrates. Two relatively new lead smelting technologies have found limited use. They are the Queneau-Schumann-Lurgi (QSL) process developed in West Germany and the Kivcet process developed in the Soviet Union. Both combine the sintering (oxidation) and blast furnace (reduction) functions into one autogenous, direct reduction unit. 5A second dressing is performed if tin removal iS necessary.

42 l Nonferrous Metals: Industry Structure bismuth (Betterton-Kroll process). The first step, softening, removes the antimony, arsenic, and tin by air oxidation in a reverberatory furnace or by the Harris process. Next, in the Parkes process, zinc is added to the melt to remove the silver and gold. The zinc, silver, and gold form insoluble compounds which are skimmed off the melt. The remaining traces of zinc are then removed by vacuum dezincing or by chlorine treatment. When necessary, bismuth is removed from the lead by the Betterton-Kroll process. The melt is treated with calcium and magnesium which alloy with the bismuth to form a crust which is skimmed off. In the United States most lead ore is smelted and refined to a minimum purity of 99.85 percent lead. Throughout the smelting and refining stages, the many dresses, slags, and slimes are worked up to recover their values of precious and base metals. THE 1980s The U.S. lead market started the 1980s on a mixed note (see figures 4-1 and 4-2). In 1980, lead prices (averaging $0.43/lb) were high compared with the late 1970s. Primary and secondary lead production (550,000 and 600,000 tonnes respectively) though were roughly equivalent to late1970s levels. Prices fluctuated downward to an average of $0.24/lb in 1982-84 and $0.21/lb in 1985-86, but then recovered to an average of $0.38/lb in 1987-89. Fluctuations in lead production levels from 1980 to 1989, left U.S. mine production down 21 percent, primary refried production down 28 percent, and secondary production up 23 percent. Secondary lead increased its importance in the U.S. market during the 1980s. The ratio of primary to secondary production shifted from roughly 50:50 in 1980 to 35:65 in 1989. 7 U.S. lead consumption held fairly steady at 1.1 million tonnes during 1980-87. It then increased slightly to 1.2 million tomes in 1987-89. For the nonsocialist world as a whole, the lead market fluctuations were more muted (see figure 4-3). The 1988 levels for NSW mine production and primary refried production were equal or slightly Figure 4-1 Lead Prices, 1975-89 Cents/pound 50 1 4 0 ~ 302010I 75-79 80 81 82 83 84 85 86 87 88 89 Year NOTE: North Ameriean primary producers list price-refined lead delivered.

Secondary lead production rose 18 percent, and consumption rose 12 percent, during 1980-88. The openings, closings, and ownership changes that occurred in the U.S. primary lead industry during the 1980s are profiled in table 4-1. Two new lead mines (West Fork and Casteel) and two lead-producing precious metals mines (Greens Creek and Montana Tunnels) opened during the decade. The Butte Hill zinc-lead-silver mine, which had been closed since the early 1970s, reopened in 1990. The Red Dog zinc-lead mine is slated to begin full production in 1990. 8 These six new mines are in Missouri, Alaska, and Montana. Two mines that produced lead were permanently closed. Many more mines closed temporarily at some time during the 1980s, because of low prices. In the processing sector, two smelters and one refinery were closed permanently, and no new ones opened. During 1980-88, U.S. smelter capacity declined 28 percent to 515,000 tonnes and refinery capacity declined 17 percent to 595,000 tonnes. Doe Run, the countrys dominant lead producer, was created in 1986 through the merger of the lead assets of Fluor and Homestake. Fluor had acquired ?~e~e fiWe~ ~epre~ent tie refined lead recovered from both new and old scrap. As such they overstate tie amomt of refined lead tit is ac~~lY entering the manufacturing stream.

Homestake had acquired full control of its lead facilities (the Buick mine and Boss smelter/refinery) earlier in 1986. During 1986-90, Doe Run was owned 57.5 percent by Fluor and 42.5 percent by Homestake. Fluor bought out Homestake in May 1990 and is now the sole owner of Doe Run. Asarco built one mine and bought another during the decade. Previously, Asarcos involvement in the lead industry had been mostly in the processing sector. Other new lead mining companies include Montana Tunnels, Greens Creek, Washington Mining, Bunker Hill Mining, Star-Phoenix Mining, New Butte Mining, and Cominco-NANA. Four companies (Ozark Lead, Bunker Hill, Amax, and Standard Metals) left the U.S. industry during the 1980s. Ozark Lead was a subsidiary of Kennecott. PRODUCER PROFILES, 1990 Lead and zinc tend to occur in the same ores, so they are often mined, and sometimes processed, jointly. The same set of countries and companies, therefore, dominate the production of both metals (see figures 4-4 and 5-4). To avoid repetition, the lead and zinc profiles of most countries are presented together in this chapter. The two industries in the United States, being more separate than those Figure 4-3--NSW Lead Production and Consumption, 1975-88 3 2 1 n 75-79 80 81 82 83 84 85 86 87 88 Year = Mine production Primary production m Secondary production Consumption NOTE: Seeondary production is refined metal reeovered from old and new scrap.

Most lead is produced in industrialized countries. Compared with copper, very little lead capacity is government-owned. Developed countries account for about 70 percent of mine capacity and even greater percentages of primary smelter/refinery capacity. 9 Australia, the United States, Canada, and Mexico are large producers in both the mining and processing sectors. Peru is a large mine producer, but has little processing capacity. Japan and Europe have large smelting/refining sectors. Secondary (recycled) lead accounts for major proportions of production in North America, Japan, and Western Europe. United States The United States is a major producer of lead, ranking second in mining and first in both primary and secondary refining. Recycled lead accounts for about two-thirds of total domestic refined production. U.S. trade in concentrates is relatively small. Concentrate imports have declined about 70 percent since the 1960s, when the United States had a large custom smelting/refining industry. Processing is now closely tied to the level of regional mine production. For refined lead, the United States imports about 12 percent of its needs. During $I.n this repo~ little distinction is made between the smelting and refining seetors of the lead industry. SmeM.ng and refining are often, though not always, carried out at the same facilities.

Doe Run Doe Run is the largest U.S. lead producer. It accounted for 56 percent of domestic mine production and 54 percent of primary refinery capacity in 1988. It operates six mines, four mills, and two smelter/refineries in the Viburnum lead belt. 12 Doe Runs Buick mine is the largest lead mine in the country. The company was established in 1986 when Fluor combined its St. Joe operations with those of Homestake 13 In May 1990, Fluor bought out Homestakes 42.5 percent share in Doe Run. Fluor has reportedly been trying to sell its share in Doe Run and sole ownership is expected to make the sale easier. 14 Lead accounts for nearly all of Doe Runs sales, but only a small part of those of Fluor. 15 Fluor is primarily an engineering, construction, and technical services company. It also has coal interests. Asarco Asarcos domestic lead operations include two lead mines in Missouri, two smelters (East Helena, Montana and Glover, Missouri), and two refineries (Omaha, Nebraska and Glover, Missouri). The company also operates the Leadville, Colorado zinc-lead-gold-silver mine which it owns jointly with Newmont. These facilities accounted for 18 percent of domestic mine production and 46 percent of refining capacity in 1988. 16 Asarco is a multinational diversified minerals producer whose primary businesses are copper, silver, gold, lead, zinc, and other nonferrous metals. Lead accounted for 6 percent of the companys sales in 1988. 17 Originally a smelting and refining company, Asarco has been trying for several years to build up its own sources of concentrates. In 1988,60 percent of the lead concentrates required by the company smelters were supplied by its own mines. This compares with 3 percent in 1985. 18 Cominco Cominco is a major Canadian minerals company that is among the worlds largest lead and zinc producers.

Chapter 4-Lead Industry l 47 Alaska, which is scheduled to begin production in 1990. 19 This mine has estimated ore reserves of 77 million tomes grading 17.1 percent zinc, 5 percent lead, and 80 grams/tonne silver. At its planned annual production of 70,000 tonnes of lead in concentrates, Red Dog will be the countrys third or fourth largest lead mine. It will increase U.S. lead mine production by 16 percent over 1989 levels. The mine will ship half of its concentrates to Comincos Trail zinc-lead smelter in British Columbia and the rest to coastal smelters in the Far East and Europe .20 Cominco also owns half of the Magmont leadzinc mine in Missouri. Magmont, which accounted for 18 percent of U.S. mine production in 1988, is currently the second largest lead mine in the country. Dresser, a machinery manufacturer, is the other owner of Magmont. Other Companies The other major firms in the U.S. lead industry are mining companies. Bunker Hill Mining, StarPhoenix Mining, and New Butte Mining operate lead-zinc mines. Hecla, Montana Tunnels (a subsidiary of Pegasus Gold), Greens Creek (a joint venture of RTZ, Hecla, Exalas Resources, and CSX Oil & Gas), and Washington Mining (in partnership with Alta Gold and Echo Bay) produce lead from precious metals mines. U.S. Interests in Other Countries The U.S.-based companies that currently have foreign lead-zinc holdings are Asarco, Phelps Dodge, and Cerro Copper, Asarco has ties to MINI, a large Australia-based producer of nonferrous metals and coal, 21 MIM has lead facilities in Australia (Mt. Isa mine) and the United Kingdom (the Britannia refinery) as well as equity interests in Cominco. Asarco also owns 34 percent of Medimsa which runs silver-lead-copper-zinc mines, mills, and smelters in Mexico. Phelps Dodge is primarily a copper company, but owns 45 percent of Black Mountain, a major lead-silver-zinc-copper mine in South Africa. Cerro Copper owns 34 percent of the Buenaventura zinc-lead mines in Peru. Two other U.S. firms have recently sold their foreign lead and zinc holdings. Amax sold its share of Fresnillo in Mexico. USX sold its share of the exhausted Prieska mine in South Africa. Canada Canada is the largest NSW zinc producing country and third ranking lead producer. 22 It is also a major exporter of lead and zinc. During 1985-88, about 40 percent of its concentrate output was exported, primarily to Japan, Belgium, and West Germany. Of its refined metal output, Canada exports about half of its lead and three-quarters of its zinc. The United States is the major destination for both refined products. Production in Canada is dominated by Cominco, Noranda, and their subsidiaries. These two companies are especially strong in the processing sector. They control all of Canadas lead processing capacity and about 70 percent of its zinc processing capacity. In the lead mining sector, they, along with the Faro joint venture, are the major producers. The zinc mining industry is somewhat more broad based, with Falconbridge, Hudson Bay, Nanisivik, and Westmin having some presence. Cominco (partially owned by Teck, MIM, and MG) is a major nonferrous metals producer. It has major zinc-lead mines in western (Sullivan, British Columbia) and northern (Polaris, Northwest Territories) Canada, and interests in mines in the United States (Magmont and Red Dog), Australia (Aberfoyle), and Spain (Exminesa). The company is especially adept at Arctic mining. Cominco has a major lead smelter and zinc electrolytic refinery at Trail, BC and an interest in the Mitsubishi-Cominco lead smelter/refinery in Japan. The Trail plant processes the concentrates from Sullivan and other Canadian mines. The company sells, buys, and toll refines large amounts of concentrates.

48 l Nonferrous Metals: Industry Structure Three-quarters of the companys sales are from the metals business, including copper, lead, zinc, silver, gold, molybdenum, cadmium, bismuth, iridium, and fabricated metals. The company also has a substantial fertilizer business. Noranda, active primarily in eastern Canada, is focused more on zinc than lead. Its Brunswick operations produce zinc-lead ore and its Ontario/ Quebec mines produce zinc-copper ore. Noranda is a diversified natural resources company with interests in nonferrous minerals and forest, energy, and manufactured products. The nonferrous segment produces zinc and lead, but also large quantities of gold, silver, and copper. 24 Norandas lead business is run through its partial ownership of Brunswick which has a mine and a smelter in New Brunswick. The zinc business is comprised of mines in Ontario and Quebec (run by Brunswick and Noranda itself) and a zinc refinery at Valleyfield, Quebec (run by the Canadian Electrolytic Zinc subsidiary). The Faro joint venture operates a large zinc-leadsilver mine in the Yukon. The mine reopened 1986 and is currently owned by Curragh Resources and Boliden. Fares concentrates are sent to the Far East and Europe for processing. Falconbridge, best known as the worlds second largest nickel producer, mines copper-zinc ores at its Kidd Creek facilities in Timmin s, Ontario. About half of the concentrates are processed onsite and the other half are shipped elsewhere. In late 1989, Falconbridge was bought by Noranda and Trelleborg of Sweden. 25 Other Canadian zinc facilities are Hudson Bays Flin Flon mine and smelter in Manitoba; Westmins Myra Falls mine in British Columbia; and the Nanisivik mine in the Northwest Territories. Hudson Bay is owned by Inspiration Resources, which in turn is controlled by Anglo American of South Africa. Westmin and Noranda are both partially owned by Brascan. Australia Australia is a major lead and zinc producer whose industries have grown significantly in the last 10 to 15 years. It exports about 90 percent of its lead and zinc output. During 1985-88, Australia exported 23 percent of its lead as concentrates (mostly to Japan and Belgium), 44 percent as bullion (to the United Kingdom), and 34 percent as refined lead. About 70 percent of the zinc exports during this period were in the form of concentrates (mostly to Japan, Europe, and South Korea), with the remainder being shipped as slab zinc. There has been a great amount of exploration and development in Australia in recent years, much of it has focused on zinc. Australias major lead and zinc companies are Pasminco and MIM. Pasminco was created by the merger of the lead and zinc operations of CRA (partially owned by RTZ) and New Broken Hill Holdings (NBHH) in July 1988. CRA and NBHH each own 40 percent of the company, the remainder is publicly held. Pasminco accounts for an estimated 45 percent of Australias lead mine production and about half of its zinc mine production. It also operates all of the countrys lead and zinc processing capacity, except for one lead bullion smelter (MIM). In terms of refried metal, Pasminco accounts for an estimated 10 percent of NSW zinc production and 7 percent of lead output. 26 Pasmincos lead-zinc mines are centered in the Broken Hill area of New South Wales. The mines have rich ores, but are considered high cost operations. The company processes concentrates from all over Australia at its Port Pirie (South Australia), Risdon (Tasmania), and Cockle Creek (New South Wales) smelters. It also operates the countrys only lead refining facility (Port Pirie). Pasmincos interests outside of Australia include the AM&S leadzinc smelter at Avonmouth in the United Kingdom and partial ownership of the Budelco zinc smelter in the Netherlands. MINI owns the silver-zinc-lead complex at Mt. Isa/Hilton (Queensland) which accounts for about 35 and 30 percent of Australias production of lead and zinc respectively. Some of the lead is shipped out as concentrates. Most, however, is smelted into bullion onsite and then shipped to the companys Britannia refinery in the United Kingdom or to Japan. All of the zinc is sold as concentrates. MIMs lead and zinc interests outside of Australia include the Britannia lead refinery, partial ownership of ~Noranda>~ alum~um smel~g facilitks are included in its manufacting sector. ~Trel]eborg a]so Oms 50 percent of Boliden, a Sweden-based nonferrous metals producer. zGIan H ammond, CRAThe Australian Connection, Engineering and Mining Journal, vol. 190, No. 8, August 1989.

Chapter 4-Lead Industry l 49 Ruhr Zink (a West German zinc refining firm) and ties to Asarco, Cominco, Teck, and Metallgesellschaft. Australias other producers operate zinc-lead mines. Aberfoyle (partially owned by Cominco) has mines at Hellyer and Que River in Tasmania. A project that quadrupled Hellyers capacity was completed in March 1989. Nicron runs the Woodcutters mine in the Northern Territory. The Cadjebut mine (owned by BHP and Billiton) in West Kimerly, West Australia began production in 1987. The Lady Loretta and Thalanga mines (owned by Pancontinental and Outokumpu) in Queensland are expected to be brought on-stream in 1990. Mexico Mexico is a medium-sized lead and zinc producer. Most of its output comes from mines where silver is the primary interest. The country exports about 60 percent of its lead and about two-thirds of its zinc. The lead is shipped mostly as refined metal. The zinc is exported as both concentrates and slab zinc. Mexican mine production is dominated by Medimsa, Penoles, Real des Angeles, and Frisco. These four companies account for about 80 percent of the countrys lead mine output and 90 percent of its zinc mine output. 27 Penoles and Medimsa operate nearly all of Mexicos lead and zinc processing capacity. Medimsa (owned by IMM and Asarco) is the largest lead and zinc producer in Mexico. It operates seven silver-zinc-lead mines, a lead smelter at Avalos Chihuahua and smelter/refinery at Monterey, and a zinc refinery at San Luis Potosi. Medimsa processes all of its output of lead concentrates, but sells or has tolled about half of its zinc concentrates. Penoles operates a number of smaller mines (either directly or through its partially owned Fresnillo subsidiary) and a large smelter/refinery at Torreon, Coahuila. The processing facility produces more lead and zinc than do the companys mines. Of the refined metal produced, roughly 60 percent of the lead and 35 percent of the zinc is based on purchased or tolled concentrates. Frisco operates two smaller silver-zinc-lead mines and has an interest in the Real des Angeles lead-zinc mine. The Real des Angeles silver-lead concentrates are processed at the Penoles smelter. Peru Peru has a medium-sized mining industry and a small processing sector. Most of the lead and zinc comes from multimetallic ores that are mined principally for their silver. Peru exports about two-thirds of its lead and zinc concentrates. Centromin (owned by the Peruvian government) accounts for about 30 percent of the countrys lead mine production and about 40 percent of its zinc mine production. The company has five silver-zinclead mines. It also has a processing plant (La Oroya) that encompasses a lead smelter/refinery and an electrolytic zinc refinery. All of Centromins lead concentrates and a quarter of its zinc concentrates are processed at La Oroya. The remainder of Perus lead and zinc mine production is from smaller local independent producers such as San Ignacio Morococha (the largest private zinc mine), Milpo (the largest private lead mine), and Atacocha. There are also some smaller mining companies held by foreign interests, including Nor Peru (partially owned by Asarco), Huaron (partially owned by Metaleurop), Santander (owned by Docarb), and Buenaventura (partially owned by Cerro Copper, Centromin, and the World Bank). Peru also has two additional processing facilities. Mineroperu (owned by the government) runs a zinc refinery at Cajamarquilla. Fundeconsa operates a small lead refinery at Sayan. Mineral production in Peru has been plagued by political strife, labor strikes, and natural disasters. These perennial problems deter foreign investment in Perus industry. Little growth is expected in Peruvian production for some time. Japan Japan has some mine production, but is primarily a processing country. It is the NSWs second largest producer of both refined lead and refined zinc. Japan imports about three-quarters of its zinc concentrates and 90 percent of its lead concentrates. Australia, Canada, and Peru are the largest suppliers. Japan is roughly self-sufficient for refined lead and a net 270r1ando Martino, The Mineral Industry of Mexico, Minerals Yearbook, vol.

50 l Nonferrous Metals: Industry Structure importer of refined zinc. The principal zinc suppliers are North and South Korea. Four companies (Dowa, Mitsui, Nippon Mining, and Mitsubishi) have both mines and processing facilities in Japan. Four others (Akita Zinc, Toho Zinc, Hachinoe, and Sumitomo) have only smelter/ refineries. The principal owners of Akita Zinc and Hachinoe are Dowa and Mitsui, respectively. All of these companies, except for Dowa in the lead sector, must purchase or toll concentrates to maintain their economic processing levels. Mitsubishi and Cominco are involved in a joint venture to process the latters Canadian lead concentrates. Spain Spain is Europes largest zinc miner and second largest lead miner. The mines, located in the southwestern part of the country, contain complex ores that are relatively difficult to process. The major lead and zinc mining companies are Exminesa, Boliden, Asturiana de Zinc, and Almagrera. Spains smelting/refining companies are Metaleurop, Asturiana de Zinc, and Espanola de Zinc. Metaleurop, which owns the largest lead smelter, produces over three-quarters of the countrys refined lead. Asturiana de Zinc, the largest zinc smelter, accounts for roughly 80 percent of Spains refined zinc output. Sweden Sweden exports about one-quarter of its lead concentrates and all of its zinc concentrates (primarily to Finland, Norway, and France). The industry is dominated by Boliden, which accounts for roughly 60 percent of the countrys lead and zinc mine production and all of its refined lead production. The company smelts its lead concentrates at Ronskar and ships the zinc concentrates to its partially owned Norzink subsidiary in Norway. Bolidens other foreign holdings include the Black Angel mine in Greenland and a small interest in the Faro mine in Canada. Most of the rest of Swedens mine output is produced by Vieille Montagne (part of Acec-Union Miniere). This companys lead concentrates are sent to Bolidens Ronskar plant; the zinc concentrates are sent to its own facilities in France. Ireland Ireland is a small zinc mine producer. It has one mine and no smelting/refining capacity. Tara (owned by Outokumpu and the Irish government) runs the Navan zinc-lead-silver mine. It is Europes largest zinc mine. The concentrates are all sent to other European countries for processing. Yugoslavia Yugoslavia has five lead-zinc producers, all of which are government-owned. RMHK Trepca is the largest. The ores are multimetallic and have a higher proportion of lead than is found in most places except the United States. Almost all of the concentrates are processed domestically. West Germany Germany is Europes largest primary lead and zinc smelter/refiner. It is also a major secondary lead producer. It imports over 80 percent of its lead concentrates and bullion. Metallgesellschaft (MG) and Metaleurop dominate production in Germany. MG runs the countrys only lead and zinc mines, and operates several smelters, through its Berzelius Metallhutten subsidiary. It also has interests in the Norddeutsche Affinerie (owned by MG, MIM, and Degussa) lead plant, and the Ruhr Zink (owned by MG and MIM) zinc plant. Metaleurop was created in 1988 by the merger of Preussag (Germany) and Penarroya (France). It is now Europes largest lead producer and second largest zinc producer (after Vieille Montagne). In Germany, Metaleurop has lead and zinc processing facilities at Nordenham. The company has additional plants in Spain and France. France France has three lead and zinc processing facilities, for which it imports most of the required concentrates. The largest concentrate suppliers are Canada, Sweden, Peru (zinc), and South Africa (lead). Metaleurop accounts for all of Frances refined lead production and about one-third of its zinc production. The company has a large complex at Noyelles-Godault, Pasde Calais. The facility is somewhat rat-e in that it produces nearly twice as much lead as zinc. The other two-thirds of the countrys refined zinc production comes from Vieille Montagnes plants at Auby. United Kingdom The United Kingdom has one primary lead refinery, the Northfleet plant run by MIMs Britannia subsidiary. This facility refines lead bullion from

PAGE 56

Chapter 4-Lead Industry l 51 the MIM Mt. Isa complex in Australia. Pasminco has a lead and zinc smelter at Avonmouth. Its lead bullion is exported to refineries in Italy, Germany, and Belgium. Belgium Belgium imports all of the concentrates needed by its lead and zinc processing industry. The largest suppliers are Peru, Australia, and Greece for lead concentrates, and Canada, France, and Mexico for zinc concentrates. Belgiums capacity is essentially all controlled by Acec-Union Miniere through two of its subsidiaries, MHO and Vieille Montagne. MHO runs all the countrys lead capacity and roughly 45 percent of its zinc capacity. The companys lead (and copper) facilities are at Hoboken and its zinc operations are at Overpelt. Vieille Montagnes Balen plant accounts for the rest of Belgiums zinc production. The Netherlands The Netherlands only primary zinc plant is Europes largest. It is run by Budelco (owned by Billiton and Pasminco) and processes concentrates from Canada, Australia, and Ireland. Italy Italy is a medium-sized zinc producer. Its industry is dominated by Metaleurops Pertusola subsidiary and Nuova Samim (partially government-owned). Pertusola accounts for about 55 percent of the countrys zinc production. Nuova Samim accounts for the remainder of the zinc and a small amount of lead production. The zinc concentrates come from Canada, Ireland, and Peru. Finland Finland has one producer, Outokumpu. It mines mostly zinc, but also a little lead. The concentrates, along with those from the Tara subsidiary in Ireland, are processed at the companys Kokkola smelter/ refinery. Norway Norways only producer, Norzink (owned by Boliden and RTZ), refines zinc at Eitrheim. The principal sources of its feed materials are Bolidens Swedish mines and smelters. 28 Other Countries Other large producers around the world include: Black Mountain and ZC South Africa in South Africa; Touissit, Djebel Aouam, and Zellidja in Morocco: CMM and Paraibuna in Brazil; Korea Zinc and Young Peon in South Korea; Padaeng in Thailand; and Gecamines in Zaire. Several of these are affiliated with companies discussed earlier: Black Mountain (Phelps Dodge) and Touissit and Djebel Aouam (Acec-Union Miniere). Recent Producer Mergers and Alliances In the late 1980s, the world lead and zinc industries went through a period of consolidation. Doe Run (United States) brought together the lead operations of Fluor and Homestake. Pasminco (Australia) was formed from CRA and NBHH. Metaleurop (France) was created through the merger of Penarroya and the lead and zinc operations of Preussag. Somewhat older are Acec-Union Miniere and the MG-MIM-Teck-Cominco-Asarco group. Acec-Union Miniere (Belgium) consists of Vieille Montagne, MHO, Asturienne, and Jersey Miniere. Interlocking ownership joins MG (West Germany), MINI (Australia), Teck (Canada), Cominco (Canada), and Asarco (United States). (See figure 4-6.) The group controls an estimated one-quarter of NSW primary refined lead production and 20 percent of primary slab zinc output. It has even greater shares in the mining sector. 29 Xwcbd H.

Chapter 5 Zinc Industry INTRODUCTION Zinc has been used in brass and bronze since ancient times. The metal was produced in its elemental form much later. In the 20th century, the invention of froth flotation spurred zinc production and the development of galvanizing increased its use. Uses Zinc is the third most used nonferrous metal, after aluminum and copper. Most primary zinc is recovered as slab. The largest use of slab zinc is for galvanizing (and electrogalvanizing), an application which accounted for 51 percent of U.S. consumption in 1988. Other uses include zinc-based die-cast alloys (23 percent), brass alloys (13 percent), chemicals, and dusts. The galvanized products are used in the steel, automobile, and construction industries. No substitute for galvanizing exists for protecting large tonnage iron and steel products from corrosion. 1 Secondary zinc, most of which comes from new scrap, is used to produce brass and bronze (46 percent of 1988 domestic use), slab zinc (26 percent), chemicals (18 percent), and dusts (7 percent). Production Methods and Technologies Zinc is produced mostly from the sulfide ores: sphalerite (ZnS) and marmatite ([Zn,Fe]S). These ores, also known as zinc blende, are commonly associated with galena, the principal lead ore. Over 80 percent of nonsocialist world (NSW) zinc mines are underground operations. After mining, the ore is crushed, ground and subjected to several froth flotation steps to remove the lead, iron, and gangue (waste rock). The resulting zinc concentrates typically contain 50 to 64 percent zinc. These beneficiation steps are performed at the minesite. 3 At the smelter/refinery, zinc is produced by one of several processes that smelt and refine the metal simultaneously. Regardless of the process, the concentrates are first roasted into zinc-oxide materials. In roasting, the concentrates are burned in the presence of oxygen (usually from air) thus forming crude zinc oxides and gaseous sulfur dioxide. Most modern roasters are fluid-bed reactors. The crude oxide is then smelted/refined by electrolytic or pyrometallurgical methods. The electrolytic process is the most common method, accounting for about 80 percent of NSW smelting/ refining capacity. In the first step of this process, the crude oxide feed is leached with sulfuric acid to produce a zinc sulfate solution. This is then purified and pumped into electrolytic cells. The cells use lead-silver anodes and aluminum cathodes. Upon application of the current, the zinc in the solution is reduced and deposited on the cathode. The cathode is stripped periodically and the zinc metal is cast into ingots. Virtually all impurities remaining from the preparation processes are eliminated. Electrolytic zinc needs no further refining. Purity normally exceeds 99.95 percent and can possibly be 99.995 percent or better. In the pyrometallurgical production methods, the crude zinc oxides from the roaster are first sintered in a Dwight-Lloyd moving grate machine or a rotary kiln to yield a homogeneous feed. The sinter is then heated to above 1,832 F (a temperature at which zinc is vapor) in the presence of a reducing agent (chiefly carbon monoxide) in one of four types of furnaces 4 This reduces and vaporizes, the zinc which is then collected in a condensation vessel.

They are pyroconcentrated at the smelter in a Waelz rotary kiln or by slag fuming. d~e four pvometal[wgica] Zin c production technologies are: the horizontal (Belgian) retort, the vertical (New Jersey) retofl, the elecmotietic (St. Joseph) retort, and the blast (Imperial Smelting) furnace. The Imperial Smelting Process (ISP), which is used primarily in Europe, Japan and Australia, is the most common. It is basically a lead blast furnace with a zinc recovery system added. It can treat mixed zinc and lead concentrates, low-grade concentrates, and oxide concentrates. The Belgian process, the oldest, is a batch method. The New Jersey and St. Joseph methods are continuous processes. A fifth pyrometallurgical technology, the Soviet-developed Kivcet process, hm found limited use. It can process lead-zinc concentrates directly, thus elimimting the need for sintering.

54 l Nonferrous Metals: Industry Structure Most of the impurities are eliminated to the furnace residues. Zinc recovered by any of the pyrometallurgical methods is less than 99 percent pure. The quality is adequate for hot-dip and continuous line galvanizing, and for some brass uses. However, for die casting, the zinc must be further refined. Fractional distillation is the most common method of upgrading the lower purity zinc. THE 1980s The U.S. zinc market started the 1980s on a mixed note (see figures 5-1 and 5-2). Prices (averaging $0.37/lb) in 1980 were slightly higher than those of the late 1970s. In 1980, domestic mine production (349,000 tonnes) was higher than it had been in the two previous years, but below what it had been for most of the 1970s. Slab zinc production (370,000 tonnes) was much lower in 1980 than it had been in previous years. The price of zinc, unlike those of the other metals in this study, remained above its 1980 level for the entire decade. The greatest increase came in the late 1980s, when zinc prices rose from $0.42/lb in 1987 to $0.83/lb in 1989. U.S. mine production fell during 1980-86. It rose in the later years, but ended the decade down 20 percent. Primary refined production, which declined sharply in 1982, finished the decade down 26 percent. Secondary zinc increased its importance in the market during the 1980s. In 1989, it accounted for 23 percent of slab zinc production in the United States. 5 Most secondary material is recovered as products other than slab zinc. The extensive use of zinc in galvanizing and other dissipative uses limits the potential for increased recycling. New scrap is principally zinc alloy and brass from manufacturing operations. U.S. slab zinc consumption rose throughout most of the 1980s. Its only large decline came during the recession in 1982. Consumption in 1989 was 21 percent greater than that in 1980 (but only 8 percent greater than the 1975-79 average). Most zinc used in the United States is imported. In 1989, total U.S. slab production (primary and scrap-based) amounted to only 34 percent of domestic consumption.

In the nonsocialist world, zinc output and use rose fairly steadily during the decade (see figure 5-3). NSW production and consumption in 1988 were both around 5.2 million tonnes, which represented a 17 percent increase over the 1980 levels. The openings, closings, and ownership changes that occurred in the U.S. primary zinc industry during the 1980s are profiled in table 5-1. Two new zinc mine (Pierrepont and Ward Mountain) and two zinc-producing precious metals mines (Greens Creek and Montana Tunnels) opened during the decade. In addition, zinc is recovered from the West Fork lead mine which opened in 1985. The Butte Hill zinc-lead-silver mine, which had been closed since the early 1970s, reopened in 1990. The Red Dog zinc-lead mine is slated to begin full production in 1990. Five zinc mines were permanently closed in the 1980s. In the processing sector, three smelter/ refineries were closed permanently and no new ones opened. During 1980-88, U.S. primary slab zinc capacity declined 44 percent to 320,000 tonnes. Acec-Union Miniere (based in Belgium) increased its position in the U.S. zinc industry in the 1980s. It acquired full control of Jersey Miniere in 1984 and purchased the USX zinc facilities in 1989. Horsehead Industries entered the industry by purchasing zinc facilities from New Jersey Zinc an d Sncse fiwres represent the slab zinc recovered from both new and old scrap.

It merged them into a venture called the Zinc Corporation of America (ZCA). Other new zinc mining companies include Doe Run, Montana Tunnels, Greens Creek, Washington Mining, Bunker Hill Mining, Star-Phoenix Mining, New Butte Mining, Alta Gold, and Cominco-NANA. Big River is the only new zinc processor. It purchased the Sauget, Illinois facility from Amax in 1988. Five companies (New Jersey Zinc, USX, Bunker Hill, Amax, and Standard Metals) left the U.S. industry during the 1980s. PRODUCER PROFILES, 1990 Most zinc is produced in industrialized countries (see figure 5-4). Compared with copper, very little zinc capacity is government-owned. Developed countries account for about 70 percent of mine capacity and even greater percentages of primary smelter/refinery capacity. 6 Canada is the largest producer in both the mining and processing sectors. Australia is a large mine producer and a mediumsized processor. Peru and Mexico have large mine production, but little processing capacity. Japan and European countries are large refined zinc producers. The United States has a medium-sized zinc industry. Inmost parts of the world, zinc and lead are mined and processed together. The situation is somewhat Figure 5-3--NSW Slab Zinc Production and Consumption, 1975-88 Million of tonnes 6 T 3 i 2 1 1 75-79 80 81 82 83 84 85 86 87 88 Year = Mine production = Primary production a Secondary production Consumption NOTE: Secondary production is refined metal recovered from old and new scrap.

The U.S. zinc and lead industries are relatively separate, though there are some domestic mines that produce both metals. United States The United States is a medium-sized zinc producer. It ranks sixth in the NSW in mine output and eighth in primary metal production. The country was a net importer of zinc concentrates during 1983-88, but a net exporter in 1989. For refined (slab) zinc, the United States is dependent on imports for about two-thirds of its needs. The major suppliers during 1985-88 were Canada (accounting for 56 percent of imports), Mexico, and Spain. Slab exports are small. About half of U.S. zinc mine production comes from Tennessee. The other major mining States are Missouri, Colorado, Alaska, Idaho, Montana, New York, and Nevada. Processing facilities are located in Tennessee, Pennsylvania, Oklahoma, and Illinois. Asarco Asarco is the largest U.S. zinc mining company (see figure 5-5). Most of its production is from its four mines in eastern Tennessee, but some also comes from its Missouri lead mines and its partially owned Leadville, Colorado operation.

Acec-Union Miniere began reorganizing its operating units Zinc Corporation of in early 1990. America Zinc Corporation of America (ZCA) is also a fully integrated producer. It accounted for an estimated 13 percent of the countrys mine production and almost one-half of the refinery capacity in 1988. ZCA has two mines in New York, a smelter/refinery in Pennsylvania, and a refinery in Oklahoma. It also processes steelmaking dusts into zinc at a plant in Pennsylvania. ZCA, a subsidiary of Horsehead Industries Inc., was formed in 1987. It represents the merger of Horseheads St. Joe operation (acquired from Fluor in 1987) and its New Jersey Zinc facilities (acquired in 1981). Doe Run Doe Run, the largest U.S. lead company, produces some byproduct zinc at its Buick mine. It accounted for 9 percent of U.S. zinc mine output in 1988. Montana Tunnels Montana Tunnels, a subsidiary of Pegasus Gold, opened its gold-silver-zinc-lead mine in 1987. The Jefferson, Montana operation accounted for 7 percent of U.S. zinc mine production in 1988. Cominco Cominco is a major Canadian minerals company that is among the worlds largest lead and zinc producers. It is developing the Red Dog mine in Alaska, which is scheduled to begin production in 1990. 9 This mine has estimated ore reserves of 77 million tonnes grading 17.1 percent zinc, 5 percent lead, and 80 grams/tonne silver. At its planned annual production of 325,000 tomes of zinc in concentrates, Red Dog will be the worlds largest zinc mine. It will nearly double U.S. zinc mine 9Cominco-Alaska is developing the mine and will operate it when it is commis sioned.

The mine will ship half of its concentrates to Comincos Trail zinc-lead smelter in British Columbia and the rest to coastal smelters in the Far East and Europe. 10 Cominco also owns half of the Magmont leadzinc mine in Missouri. Magmont, which is currently the second largest lead mine in the country, accounted for 3 percent of U.S. zinc mine production in 1988. Dresser, a machinery manufacturer, is the other owner of Magmont. Big River Big River bought the Sauget, Illinois smelter/ refinery from Amax Zinc in 1988. The plant accounts for about a quarter of domestic zinc processing capacity. The company has no mines. Other Companies The other major firms in the U.S. zinc industry are mining companies. Alta Gold recently opened a zinc mine in Nevada. Bunker Hill Mining, Star-Phoenix Mining, and New Butte Mining operate lead-zinc mines. Hecla, Greens Creek (a joint venture of RTZ, Hecla, Exalas Resources, and CSX Oil & Gas), and Washington Mining (in partnership with Alta Gold and Echo Bay) produce zinc from precious metals mines. U.S. Interests in Other Countries The U.S.-based companies that currently have foreign lead-zinc holdings are: Asarco, Phelps Dodge, and Cerro Copper. Asarco has ties to MIM, a large Australia-based producer of nonferrous metals and coal. ll MIM has lead facilities in Australia (Mt. Isa mine) and the United Kingdom (the Britannia refinery) as well as equity interests in Cominco. Asarco also owns part of Medimsa which runs silver-lead-copper-zinc mines, mills, and smelters in Mexico. Phelps Dodge is primarily a copper company, but owns part of Black Mountain, a major lead-silver-zinc-copper mine in South Africa. Cerro Copper has interests in the Buenaventura zinc-lead mines in Peru. Two other U.S. firms have recently sold their foreign lead and zinc holdings. Amax sold its share of Fresnillo in Mexico. USX sold its share of the exhausted Prieska mine in South Africa. Other Countries Zinc and lead are often produced by the same set of countries and companies.
