How aluminum is made

Bauxite consists mostly of the aluminium minerals gibbsite (Al(OH) 3) boehmite (γ-AlO(OH)) and diaspore (α-AlO(OH)) mixed with the two iron oxides goethite (FeO(OH)) and haematite (Fe 2 O 3) the aluminium clay mineral kaolinite (Al 2 Si 2 O 5 (OH)) and small amounts of anatase (TiO 2) and ilmenite (FeTiO 3 or FeO TiO 2)
