This aluminium oxide is dissolved at a temperature of about 960 °C (1,760 °F) in molten cryolite. Next, this molten substance can yield metallic aluminium by passing an electric current through it in the process of electrolysis, which is called the Hall–Héroult process, named after its .
BAUXITE MINING. The aluminium production process starts with the mining of bauxites, an aluminium rich mineral in in the form of aluminium hydroxide. About 90% of global bauxite supply is found in tropical areas.
Aluminium in Africa originates primarily in Guinea, Mozambique and Ghana. Guinea is by far the biggest producer in Africa, and is a world leader in aluminium and bauxite production; see "World bauxite mine production, reserves, and reserve base" at the bauxite article. There are many companies involved in the aluminium trade in Africa.

Using the Bayer process, alumina (aluminium oxide) is extracted from bauxite in a refinery. The alumina is then used to produce the primary metal at a ratio of 2:1 (2 tonnes of alumina = 1 tonne of aluminium). 3. Primary production. The aluminium atom in alumina is bonded to oxygen and needs to be broken by electrolysis to produce aluminium metal.
Aluminium is the most profuse metallic part in the earths crust. It is mined from bauxite-contained mining areas since the production of aluminium is entirely reliable on extraction from bauxite. It is not found in free form and is the most abundant metallic element in the Earth's crust. Alumininum is basically obtained by using a technique called the Bayer's process developed by Karl Joseph ...
