Aluminum Production
Initially, bauxite is extracted by mining. Then, it is converted to alumina via the Bayer process. According to the worldwide average, 2.3 tons of bauxite is necessary to produce 1 ton of alumina. Primary aluminum is produced via the Hall–Héroult process, a process of electrolytic reduction in a molten bath of natural and synthetic cryolite.
