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.

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.
The bauxite residue is safely stored, in ways which meet industry best practice and required safety standards. One technique used for bauxite residue storage in Australia is "dry stacking'", which involves depositing and drying the residue in thin layers to a high density, thus making it very stable and unlikely to flow in the event of a ...
