Bauxite Wikipedia

Bauxite, an aluminium ore, is the world's main source of aluminium. It consists mostly of the minerals gibbsite (Al(OH) 3), boehmite (-AlO(OH)) and diaspore (-AlO(OH)), mixed with the two iron oxides goethite and haematite, the clay mineral kaolinite and small amounts of anatase (TiO 2) and ilmenite (FeTiO 3 or FeO.TiO 2)....
