Aluminum Corporation of China

Aluminum Corporation of China Limited (Chalco) has masterminded its way into mixing alumina and aluminum. Chalco is the only maker of alumina -- which is refined from bauxite and a key material in producing aluminum -- in China. The company produces about 9 million tons of alumina products (including alumina, alumina hydrate and alumina chemicals), which makes it the second-largest maker of alumina in the world. Chalco also produces a million tons of primary aluminum annually. In 2007 the company agreed to acquire sister company Baotou Aluminum for about $2 billion. Chinalco, a state-owned enterprise, owns 40% of the company. http://www.hoovers.com/aluminum-corporation-of-china/--ID__115289--/free-co-profile.xhtml/
