Bauxite mining-HYDRO

Aluminium production starts with the raw material bauxite. Bauxite is a mineral found mostly in a belt around the equator. Bauxite, containing 15-25 percent aluminium, is the only ore that is used for commercial extraction of aluminium today.

Aluminium production process

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. About 90% of global bauxite supply is found in tropical areas.


Bauxite residue is mainly composed of iron oxides, titanium oxide, silicon oxide and un-dissolved alumina together with a wide range of other oxides which will vary according to the country of origin of the bauxite.

How aluminium is produced

The next stage in the production chain is the processing of bauxite into alumina, or aluminium oxide - Al 2 O 3, - a white powder. The most common process for making alumina from bauxite is the Bayer process, which was first discovered over 100 years ago but is still in wide use today.
