List of countries by bauxite production

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 TiO 2, Ilmenite, FeTiO 3, and FeOTiO 2.
