Aluminum and Aluminum Castings | Metal Casting Resources
Aluminum processing. Bauxite is a sedimentary rock containing high aluminum content; typically, about 46–60%. Bauxite is often covered by several meters of rock and clay, which must first be removed before the bauxite can be recovered. The bauxite then goes through crushing or washing plants before being transported for processing.

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.
