Extraction of Aluminium
Bauxite Mining. Various minerals can be used in the aluminium extraction process. The most commonly used raw material is bauxite, which is made up of a combination of aluminium oxide, mixed with other minerals. During mining, bauxite is classified depending on the percentage of aluminium oxide it contains.

Bauxite: The principal ore of aluminum.
Physical Properties of Bauxite. 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.

Energy needed to produce aluminum
Bauxite is then converted into aluminum oxide, or alumina, using natural gas at plants located in the southern United States. After alumina is extracted from bauxite ore, further processing called 'smelting' is necessary to convert it into aluminum. In this process, alumina is dissolved in a solution and a strong electric current is applied.
