Aluminum Corporation of China Limited (Chinalco) has masterminded its way into mixing alumina and aluminum. Chinalco is the only Chinese maker of alumina, which is refined from bauxite and is the key material in producing aluminum. In 2014, the company produced about 12 million tons of alumina products (including alumina, alumina hydrate, and alumina chemicals), which makes it the largest alumina producer in China and the second-largest maker of alumina in the world. Chinalco also produced more than 3.4 million tons of primary aluminum and 800,000 tons of fabricated aluminum products in 2014. The company is also looking to develop rare earth metals as well as copper and other nonferrous metals.
