· Bauxite is a mineral that contains varying amounts of combined water and several impurities of which ferric oxide and silica are usually predominant. It is found in a belt around the equator and is generally extracted by open-cast mining. Before mining can commence the land needs to be cleared of timber and vegetation.

Aluminium Ore. Bauxite is the name given to aluminium ore. To generate aluminium oxide, bauxite is purified, a white powder form which aluminium can be extracted. Aluminium oxide has a very high melting point of more than 2022 ° C so melting it would be costly. Aluminium oxide in water does not dissolve, but in molten cryolite, it dissolves
