Bauxite
Bauxite is a sedimentary rock with a relatively high aluminium content. It is the world's main source of aluminium and gallium. 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 (FeO(OH)) and haematite (Fe2O3), the aluminium clay mineral kaolinite (Al2Si2O5(OH)4) and small amo…

Compilation of Gallium Resource Data for Bauxite Deposits
typical bauxite rock also contains a mixture of goethite (FeO(OH)), hematite (Fe 2 O 3), the clay mineral kaolinite, and a minor amount of anatase (TiO 2). The formation of bauxites requires intense weathering in tropical or subtropical climates (Bárdossy, 1994). Bauxites typically occur within the thick profiles of laterites, which are formed by

Bauxite: The principal ore of aluminum.
Bauxite is typically a soft material with a hardness of only 1 to 3 on the Mohs scale. It is white to gray to reddish brown with a pisolitic structure, earthy luster and a low specific gravity of between 2.0 and 2.5. These properties are useful for identifying bauxite; however, they have nothing to do with bauxite's value or usefulness.
Bauxite and Alumina Statistics and Information
Bauxite is a naturally occurring, heterogeneous material composed primarily of one or more aluminum hydroxide minerals, plus various mixtures of silica, iron oxide, titania, aluminosilicate, and other impurities in minor or trace amounts. The principal aluminum hydroxide minerals found in varying proportions with bauxites are gibbsite and the ...
