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.
The first step in producing aluminium is mining its ore bauxite.Bauxite occurs mainly in tropical and sub-tropical areas, like Africa, the West Indies, South America and Australia there are some small deposits located in Europe. Australia is the largest producer of bauxite, with five mines supplying around 23 per cent of global production.

Characterization of bauxite fines aiming to minimize their iron content. Samples of the fine and superfine bauxite products from Porto Trombetas were studied in order to make possible the evaluation of the occurrence of iron bearing minerals and to verify the possibilities of minimizing their content. The bauxite ore resulted from an in
Bauxite tailings, also known as bauxite residue, red mud, red sludge, or alumina refinery residues (ARR), is a highly alkaline waste product composed mainly of iron oxide that is generated in the industrial production of alumina (aluminium oxide, the principal raw material used in the manufacture of aluminium metal and also widely used in the manufacture of ceramics, abrasives and refractories).

Bauxite. Bauxite is the most important ore of aluminum which contains only 30–54% alumina, Al2O3; the rest is a mixture of silica, various iron oxides, and titanium dioxide along with trace amounts of zinc, phosphorous, nickel, vanadium etc., as indicated earlier.
alumina to aluminum metal. It starts with the mining of bauxite ore, a hydrated oxide of aluminum consisting of 36 to 56 percent alumina (Al2O33) and lesser amounts of iron, silicon, and titanium. The Bayer process is used to refine bauxite into alumina. The Hall-Heroult process is used to reduce alumina to aluminum metal by electrolytic reduction.
is doing a good work in the aspect of how mining is destroying the lives of people in several parts of the world. Mr. Moody said the worst result of bauxite mining would be destruction of the unique system of bauxite retaining the water like a sponge
Conditions within the digester (caustic concentration, temperature and pressure) are set according to the properties of the bauxite ore. Ores with a high gibbsite content can be processed at 140°C, while böhmitic bauxites require temperatures between 200 and 280°C.
