The principal minerals in bauxite are gibbsite (Al 2 O 3.3H 2 O), boehmite (Al 2 O 3.H 2 O) and diaspore, which has the same composition as boehmite but is denser and harder. Bauxite is usually classified according to its intended commercial application, e.g., metallurgical, cement, fertiliser, abrasive, chemical or refractory.

Bauxite is a mixture of minerals which contain, as well as impurities, different concentrations of hydrated aluminium oxides. Gibbsite (alumina trihydrate), boehmite, and diaspore (alumina monohydrates) are the main ore minerals. Bauxite is a high-aluminium-content rock. That is the main ore that aluminium is mined from.

Bauxite is the main ore of aluminium and to be commercially exploited should contain more than 25–30% aluminium oxide. The main constraint is the amount of available alumina which can be extracted by the Bayer or similar process. It is named after Les Baux de Provence, in southern France; the major producers are Australia and Brazil.

Bauxite has a low Mohs hardness of 1.5-3.0, a dull, earthy luster, and low specific gravity of 2.0-2.5. Bauxite forms in moist tropical or subtropical climates when the aluminum-silicate minerals in clayey soils are leached and converted to basic oxides. Typically large and shallow, bauxite deposits are eminently suited for inexpensive strip ...
