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 electrolytic reduction to aluminum.
Bauxite is extracted through open cast mining and converted to alumina, usually close to the mine. The alumina powder is shipped to aluminum smelters worldwide where it is smelted and cast into aluminum billets, blocks, and ingots before being cut to manageable sizes using large circular saws.
