Bauxite Wikipedia

Bauxite is a sedimentary rock with a relatively high aluminium content It is the world's main source of aluminium and galliumBauxite consists mostly of the aluminium minerals gibbsite (Al(OH) 3), boehmite (γAlO(OH)) and diaspore (αAlO(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) 4) and small
