Aluminium | Geoscience Australia
Bauxite is the most common aluminium ore. Bauxite occurs as a weathered cover or blanket, known as laterite or duricrust, over a variety of alumina-bearing rocks. It forms when large amounts of rainfall leach away the more mobile elements in the host rock leaving the relatively immobile aluminium with some silicon, iron and titanium.

Aluminum facts
The production of primary aluminum metal begins with bauxite ore, which is composed of hydrated aluminum oxide (40% to 60%) mixed with silica and iron oxide. It takes approximately 4 to 5 tonnes of bauxite ore to produce 2 tonnes of alumina. In turn, it takes approximately 2 tonnes of alumina to produce 1 tonne of aluminum.

Extraction of Aluminium (Aluminium Ore)
Bauxite is the name given to aluminium ore. To generate aluminium oxide, bauxite is purified, a white powder from which aluminium can be extracted. Aluminium oxide has a very high melting point of more than 2000° C which makes melting very expensive. Aluminium oxide in water does not dissolve, but in molten cryolite, it dissolves.

Aluminium Metallurgy
The ore is first converted into pure aluminum oxide by the Bayer Process, and this is then electrolyzed in solution in molten cryolite - another aluminum compound. The aluminum oxide has too high a melting point to electrolyse on its own. The usual aluminum ore is bauxite. Bauxite is essentially an impure aluminum oxide.
