Alumina To Aluminium

Alumina Refining | The Aluminum Association

Alumina is the common name given to aluminum oxide (Al 2 O 3). Alumina is produced from bauxite, an ore that is mined from topsoil in various tropical and subtropical regions. The Bayer process, discovered in 1887, is the primary process by which alumina is extracted from bauxite.

Alumina, or aluminum oxide (Al2O3– the material resulting from the Bayer Process – is a chemical compound that can be refined to produce aluminum. Refining Alumina into Aluminum The conversion of alumina to aluminum is carried out via a smelting method known as the Hall-Heroult Process.

Alumina Limited

Alumina is converted into aluminium by dissolving it in an electrolytic bath of molten cryolite (sodium aluminium fluoride) within a large carbon or graphite lined steel container known as a "pot". An electric current is passed through the electrolyte at low voltage, but very high current.


Alumina, or aluminium oxide, is the largest single cost in connection with aluminium production. Top quality alumina is required to produce quality metal with low environmental impact. The worldwide production of close to 100 millions tonnes is mainly produced from bauxite in the Bayer process.
