Bauxite ore is the main source of aluminum and contains the aluminum minerals gibbsite, boehmite, and diaspore. Aluminum is used in the United States in packaging, transportation, and building. Because it is a mixture of minerals, bauxite itself is a rock, not a mineral.
Bauxite does not make aesthetic or interesting specimens as far as collectors are concerned, but it holds importance as being the primary ore of the metal aluminum. Bauxite is named after the French village of Les Baux, where it was first recognized as an aluminum ore .
Bauxite is the primary raw material for refining aluminium oxide, or alumina, which is used to produce primary aluminium metal. Alumina is refined bauxite and is a raw material for making aluminium The raw material required for the production of primary aluminium is aluminium oxide, or alumina, a white powder refined from bauxite.
The primary source of aluminum is an ore known as bauxite. An ore is any naturally occurring solid material from which a metal or valuable mineral can be obtained. In this case, the solid material is a mixture of hydrated aluminum oxide and hydrated iron oxide.
Since 1996, McGeorge Contracting Co., based in Little Rock, has been custom mining bauxite for nonmetal uses. Bauxite is a nonrenewable resource that has directly added significantly to the economic development of Arkansas, both directly and through associated industries and suppliers.

In its mineral form Bauxite, Aluminum is the most abundant metal in the earth's crust. Bauxite contains one of a variety of hydrated aluminum oxides (gibbsite, boehmite or diaspore), which are often expressed as Al 2 O 3 xH 2 O but are more commonly regarded as impure Al 2 O 3 .
Bauxite: 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,

Bauxite is the main raw material used in the commercial production of alumina (Al 2 O 3) and aluminium metal, although some clays and other materials can be utilised to produce alumina. Bauxite is a heterogeneous, naturally occurring material of varying composition that is relatively rich in aluminium.

Bauxite ore is the world’s primary source of aluminum. The ore must first be chemically processed to produce alumina (aluminum oxide). Alumina is then smelted using an electrolysis process to produce pure aluminum metal.
Bauxite normally contains 3060% aluminum oxide (commonly referred to as alumina) and is regularly found near the earth's surface. This process can be separated into two parts; (1) the extraction of alumina from bauxite, and (2), the smelting of aluminum metal from alumina.
Aluminum originates from bauxite, an ore typically found in the topsoil of various tropical and subtropical regions. Once mined, aluminum within the bauxite ore is chemically extracted into alumina, an aluminum oxide compound, through the Bayer process.
