The first step in producing aluminium is mining its ore – bauxite. Bauxite is generally extracted by open cast mining, being almost always found near the surface Bauxite occurs mainly in tropical and sub-tropical areas, like Africa, the West Indies, South America, Australia & India – there are some small deposits located in Europe.

Unlike the base metal ores, bauxite does not require complex processing because most of the bauxite mined is of an acceptable grade. Ore quality can be improved by relatively simple and inexpensive processes for removing clay, known as “beneficiation”, which include washing, wet screening and mechanical or manual sorting.

Dry beneficiation of bauxite minerals for greater yields. The primary starting material for aluminum refining is bauxite. Since aluminum is a reactive element and does not occur naturally, aluminum-rich ore needs to be refined to produce alumina and aluminum, resulting in a significant generation of by-product residue.
