12.1 Primary Aluminum Production

12.1.2 Process Description 2-3 Primary aluminum production begins with the mining of bauxite ore, a hydrated oxide of aluminum consisting of 30 to 56 percent alumina (A l2O3) and lesser amounts of iron, silicon, and titanium. The ore is refined into alumina by the Bayer process. The alumina is then shipped to a primary aluminum plant for


mines and brought to Alcoa'sore shed for storage. Crushing will take place on a temporary basis in a cyclic process. Bauxite will be stock piled until there is enough ore to be crushed. For example, ore may be stock piled for 3 months, the crusher operated for 3 weeks, and the cycle repeats. The ore is sold after crushing.
