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 and haematite, the aluminium clay mineral kaolinite and small
