bauxite, rock largely composed of a mixture of hydrous aluminum oxides. Bauxite is the principal ore of aluminum. Bauxites vary physically according to the origin and geologic history of their deposits: some deposits are soft, easily crushed, and structureless; some are hard, dense, and pisolitic, or pealike; still others are porous but …

Bauxite (Aluminium) Colour: Shades of brown, red-brown, and yellow-brown. Name: After the locality at Baux (or Beaux), near St. Reny, Bouches-du-Rhône, France. Predominantly hydrated aluminium oxides with iron oxides, kaolinite and other impurities; almost always a residual soil rather than a sediment. Note that iron-rich sediments are covered ...

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 ...

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.

What the meaning of Bauxite ? Bauxite is the most important aluminum ore. This type of rock consists mainly of the minerals gypsite Al(OH)3, bohemite γ-AlO(OH), anddiaspore α-AlO(OH) in a mixture that usually includes iron oxide goethite,hematite,the clay mineral kaolin, and small amounts of titanium minerals such as anatite, TiO2,ilmenite, and …

During the 1950s bauxite export was focused on 1) higher grade calcined bauxite (for which Guyana had an effective monopoly); and 2) processing of primary bauxite into alumina, beginning in 1956 ...

Aluminum ore, also known as bauxite, is a naturally occurring mineral rock that contains aluminum in the form of aluminum oxide (Al2O3) mixed with various impurities. Bauxite is the primary source of aluminum, which is one of the most abundant elements in the Earth's crust, comprising about 8% by weight. Bauxite.
