Bauxite is the most important aluminum ore. This form of rock consists mostly of the minerals gibbsite Al(OH)3, boehmite γ-AlO(OH), and diaspore α-AlO(OH), in a mixture that usually includes the two iron oxides goethite and hematite, and may include the clay mineral kaolinite, and small amounts of the titanium minerals anatase TiO2, Ilmenite, FeTiO3, and FeOTiO2.[1][2] Bauxite was named after the village Les Baux in southern France, where it was first recognised as containing aluminium and named by the French geologist Pierre Berthier in 1821.
