　　We are the only producer of alumina and the largest producer of primary aluminum in China, the fastest growing major aluminum market in the world. Alumina and primary aluminum are our principal products. Alumina is refined from bauxite through a chemical process and is the key raw material for producing primary aluminum, which in turn is a widely used metal and the key raw material for aluminum fabrication.
　　We produced approximately 4.3 million tonnes of alumina products (including alumina, alumina hydrate and alumina chemicals) in 2000, which supplied approximately 70% of all alumina products consumed in China in that year and which made us the third largest producer of alumina in the world. Our alumina production has increased rapidly in the past five years, and we expect to continue to capture the growth of China's alumina market through ongoing expansion. From 1996 to 2000, our alumina production grew at a compound annual rate of 14.0%.
　　Our primary aluminum production (including aluminum ingots and other primary aluminum products) of 669,800 tonnes in 2000 accounted for approximately 23.7% of China's domestic primary aluminum production and approximately 20.8% of domestic primary aluminum consumption for 2000. From 1996 to 2000, our primary aluminum production grew at a compound annual rate of 12.1%.Sales of our alumina and primary aluminum products combined accounted for 95.0% and 92.5% of our total revenues in 2000 and in the six months ended June 30, 2001,respectively.
　　Our key operating assets include four integrated alumina and primary aluminum production plants, two alumina refineries, one primary aluminum smelter and one research institute. Our refineries are located in reasonable proximity to abundant bauxite reserves .The map below indicates the locations of our alumina refineries, primary aluminum smelters and Research Institute in China.

　We were established on September 10, 2001 as part of the restructuring of China's state-owned aluminum industry. Aluminum Corporation of China, or Chinalco, was formed on February 21, 2001 to own and operate 12 state-owned entities engaged in the production and distribution of alumina, primary aluminum, fabricated aluminum products and other products. In connection with our formation, Chinalco transferred to us substantially all of its business and assets relating to the production and sales of alumina and primary aluminum in exchange for shares in our company.

Chalco , Aluminum Corporation of China Limited , is the sole producer of alumina and gallium and also the largest producer of primary aluminum , alumina chemicals , anode and cathode blocks in China. Its main assets include four integrated alumina and aluminum plants ( Shandong Branch , Zhengzhou Branch , Guizhou Branch and Pingguo Branch ) , two alumina refineries ( Shanxi Branch and Zhongzhou Branch ) , one aluminum smelter ( Qinghai Branch ) and one research institute (Zhengzhou Light Metals Research Institute).

The Guangxi Branch 広西壮族自治区
The Guangxi Branch commenced operations in 1994 and is located in Guangxi Zhuang Autonomous Region in southwestern China, an area rich in bauxite resources. The Guangxi Branch is our newest alumina and primary aluminum plant, and is equipped with imported facilities and technology. It is one of the most technologically advanced alumina and primary aluminum plants in China. It is also the third largest smelter in China in terms of production volume.

Guizhou Branch 　貴州
Our primary aluminum production facilities in Guizhou Branch Province commenced operations in 1966 and have undergone numerous upgrades in technology since its establishment. With an annual production capacity of 235,000 tonnes, the Guizhou Branch is China's largest primary aluminum plant in terms of production volume. Its primary aluminum facilities consist of three large-scale pre-baked reduction pot-lines, ranging from 160 kA to 186 kA. As a result of technological innovations and overhauls since its inception, our Guizhou Branch is among the most technologically advanced smelters in China. Its primary aluminum products are sold primarily in southwestern China.

Zhengzhou Branch　河南省鄭州
Our Zhengzhou Branch is located in Zhengzhou, Henan Province, a province rich in bauxite resources. Its alumina and primary aluminum production commenced operations in 1966 and 1967, respectively. The Zhengzhou Branch was the first refinery in China to develop the hybrid Bayer-sintering process. Since its inception, its production facilities have undergone substantial technological upgrades, based on equipment imported from Germany and Denmark. The refinery has also benefitted from its access to high alumina-to-silica ratio bauxite from our own mines and through local market purchases. It retains part of its alumina output for its primary aluminum production, and sells the remainder to our other smelters and external customers.

Shandong Branch 　山東
The Shandong Branch commenced operations in 1954 and has both alumina and primary aluminum production capacity. Its refinery was China's first production facility for alumina. Both the refinery and smelter are owned and operated by Shandong Aluminum, a joint stock limited company whose class A ordinary shares have been publicly offered to investors in the PRC and are listed on the Shanghai Stock Exchange. We currently hold a 71.4% equity interest in this listed company.
The Branch produces the majority of its alumina through the sintering process, but has a small production line to produce alumina through the Bayer process using imported bauxite. The Bayer production line is currently being converted into an ore-dressing sintering operation. The Shandong Branch purchases the majority of its bauxite requirements from small independent mines in Henan and Shanxi Provinces. The refinery supplies all of the alumina needs for the Branch's primary aluminum production.

Qinghai Branch　青海
Located in Qinghai Province, our Qinghai Branch is a stand-alone primary aluminum production facility and is also China's second largest smelter by production volume. This Branch commenced operations in 1987, and together with our Guangxi and Guizhou Branchs, stands at the technological forefront of primary aluminum smelters in China. It operates automated 160 kA pre-baked anode reduction pot lines that were developed domestically. It benefits from relatively low electricity costs in Qinghai Province resulting from substantial hydroelectric power stations in the region. Historically, the Branch has relied on our hanxi, Shandong, Zhengzhou and Zhongzhou Branchs for its alumina supply, as well as imported alumina. Because of its relatively remote location, the Branch incurs higher transportation costs for both raw materials and its primary aluminum products. It sells its products in southwestern and southern China.

Shanxi Branch　山西
The Shanxi Branch commenced operations in 1987 and is located in Shanxi Province, a province with the largest bauxite deposits in China. Our Shanxi Branch is a stand-alone alumina Branch and is currently China's largest alumina Branch in terms of production volume.
The Shanxi Branch's production facilities are primarily imported and are technologically advanced compared with other domestic alumina refineries. A portion of the facilities are currently undergoing technical upgrade, the completion of which is scheduled during 2000. The Branch relies on bauxite from our own mines as well as outside purchases principally from Henan Province. In close proximity to large coal mines and substantial water resources, the Branch currently has the largest power cogeneration capacity of all of our alumina Branchs. It has historically been a main supplier of alumina to our Qinghai Branch and sells the rest of its output in northern and northeastern China.

Zhongzhou Branch　河南省
Situated in Henan Province, our Zhongzhou Branch is a stand-alone alumina Branch, located near bauxite, coal and water supplies. The Branch commenced operations in 1993 and is equipped with imported and self-developed technology and has undergone various improvements and upgrades, including improved sintering technology. It sources bauxite in Henan and Shanxi Provinces. The Branch's alumina and other alumina products are sold mainly within Henan Province and it is also a supplier of alumina to our Qinghai Branch.

Qingtongxia Aluminium　　

Qingtongxia 青銅峡　Aluminium, located in western Ningxia Autonomous region, was founded in 1964. It has hydropower and coal-fired power stations. The company set up the country's first aluminum joint venture with Alcan, the world's second- biggest aluminum producer, two years ago, including a 150,000- ton smelter and a coal-fired power plant.

Qingtongxia Aluminium ranks behind Aluminum Corp. of China Ltd. in Chinese production. It has capacity of more than 400,000 tons a year on top of the Alcan venture. It aims to double production to 700,000 tons by 2010, with profit exceeding 1 billion yuan ($125 million), the company said on its Web site.

The company's integrated hydro and coal-fired power stations probably added to its attraction for Glencore, said Antaike's Wang. Antaike is a research affiliate of the China Nonferrous Metals Industry Association, and advises government on industry policies. Power accounts for a third of the cost of producing aluminum.

2006/8/12 Shanghai Daily

Swiss firm eyes China aluminum deal

GLENCORE International AG, a Switzerland-based commodities trader, plans to buy a stake in China's second-biggest aluminum maker by output, a source close to the deal told Shanghai Daily.

Glencore has entered into a memorandum of understanding with state-owned Qingtongxia Aluminum Group Co for the acquisition, the Swiss company's first aluminum investment in China.

The size and price of the stake will be decided after due diligence is completed. The deal can be finalized either by purchasing existing shares or for Qingtongxia to issue new shares via a private placement, the source said.

"On one hand, the company buys into a Chinese aluminum producer to secure resources as global demand rises," Pan Shifei, an analyst at Northeast Securities Co in Shanghai, said after being informed of the possible deal. "On the other, capacity in Europe is declining because of higher energy costs and environmental concerns."

Qingtongxia was founded in 1964 in the northwestern Ningxia Hui Autonomous Region. It operates hydro and coal-fired power stations. The firm is ranked second in China's aluminum business after Beijing-based industry leader Aluminum Corp of China.

Qingtongxia earlier set up an aluminum joint venture with Montreal-based Alcan Inc, the world's second-largest aluminum producer, in Ningxia autonomous region.

GLENCORE International AG 　http://www.glencore.com/

Founded in 1974, Glencore initially focused on the physical marketing of Ferrous and Non-Ferrous Metals, Minerals and Crude Oil. Subsequently, the Company expanded into Oil Products and Coal as part of the Energy Products group. The acquisition of a well established Dutch Grain marketing company in 1982 created the basis for the Agricultural Products group.

Following the acquisitions of interests in production assets in mining, smelting, refining and processing, Glencore evolved from a pure physical commodity marketing company into a diversified natural resources group.

In 1987, a subsidiary of Glencore acquired 27% of the Mt. Holly Aluminium smelter in the United States. The first controlling interest in an industrial asset was secured in 1988, with the purchase of a 66.7% interest in Perubar, a Zinc/Lead mine in Peru. Today, the Company and its subsidiaries own and operate 18 large scale production assets across a range of commodities. In addition, Glencore directly or through its subsidiaries holds significant stakes in publicly listed companies Xstrata Plc. (UK), Century Aluminum (USA) and Minara Resources (Australia).

Glencore is a privately held company, wholly owned by its management and key employees.
This structure aligns the interests of shareholders with management and has developed the strong culture of excellence and teamwork which has been an important element of the Company's successful growth over the past 32 years.

The Swiss company already directly controls aluminum smelters with a capacity of 385,000 metric tons. It also owns 29 percent of the shares in Century Aluminum Co., North America's third-largest producer.

Century Aluminum was formed in 1995 by Glencore International of Switzerland as a holding company for its aluminum-producing assets. These assets consisted of Ravenswood Aluminum Corporation, an integrated producer of rolled aluminum products at Ravenswood, WV; a 26.67-percent share in a 215,000 metric-ton-per-year (mtpy) aluminum reduction plant at Mt. Holly, SC; and an alumina refinery in St. Croix that was subsequently sold.
Century became publicly owned in March 1996.

Aluminium · Alumina · Bauxite

Glencore and its subsidiaries are involved in all stages of the production of primary aluminium.  This includes the mining of Bauxite and refining of Alumina as feedstock for production assets owned by our subsidiaries, as well as for world markets. Glencore and its subsidiaries are also large participants in the marketing of both Aluminium and Alumina from world markets, as well as from the owned industrial assets.

The supply sources and customer bases are well diversified and underline our reputation for strong relationships amongst both market segments. Through the physical exchange of
Bauxite and Alumina of different origins, Glencore helps to optimise the production systems of a number of integrated Aluminium and Alumina producers, including those production assets owned by our subsidiaries.
