The smelting of aluminum begins with the extraction of bauxite ore by a form of open cast mining. The bauxite is washed and screened before being converted to alumina, a white powdery element from which the aluminum is produced. Aluminum smelting is carried out in a Hall Heroult reduction cell, which is lined with carbon. A mix of alumina and cryolite is fed into the cell and carbon blocks

Bauxite is an aluminium ore and is the main source of aluminium. This form of rock consists mostly of the minerals gibbsite Al(OH)3, boehmite y-AlO(OH), and diaspore a-AlO(OH), in a mixture with the two iron oxides goethite and hematite, the clay mineral kaolinite, and small amounts of anatase TiO2 A brownish-yellow clay-like and earthy mineral.

“Mining” is the work of digging up ore from the mineral deposits where it is found. In the case of copper, the actual copper to be mined makes up only about 0.3 to 1% of the overall ore. Excavated ore requires a process called “beneficiation,” which separates useful minerals from the rest of the ore.
