Mining and Refining – Process - World Aluminium

Mining and Refining – Process Aluminium is the most abundant metal in the earth's crust. The aluminium-containing bauxite ores gibbsite, böhmite and diaspore are the basic raw material for primary aluminium production. Proven, economically viable reserves of bauxite are sufficient to supply at least another 100 years at current demand.

How aluminium is produced

The aluminium production process can be broken down into three stages; first bauxites, which contain aluminium, are extracted from the ground. Second, bauxites are processed into alumina or aluminium oxide, and finally in stage three, pure aluminium is produced using electrolytic reduction, a process in which aluminium oxide is broken down into its components using electric current. About 4-5 ...
