Bauxite

Approximately 85% of the world’s bauxite production is metallurgical bauxite and the alumina is extracted from the bauxite in a refinery using a wet chemical caustic soda leach process known as the Bayer process The alumina is then converted to aluminium metal via electrolysis in a smelter using the energy-intensive Hall-Heroult process Bauxite formation Bauxite ,

121 Primary Aluminum Production - US EPA

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 The ,
