Bauxite is a sedimentary rock with a relatively high aluminium content. It is the world's main source of aluminium. 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 (Fe₂O₃), the aluminium clay mineral kaolinite (Al₂Si₂O₅(OH)) and small amounts of anatase (TiO₂) and ilmenite (FeTiO₃ or FeO.TiO₂).
