Bauxite Processing Mining

Mining and Refining – Process

The bauxite residue sinks to the bottom of the settling tanks, then is transferred to the washing tanks, where it undergoes a series of washing stages to recover the caustic soda (which is reused in the digestion process). Further separation of the pregnant liquor from the bauxite residue is performed utilising a series of security filters.

Mining and Refining – Process - World Aluminium 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.

Bauxite - Wikipedia

Bauxite is a sedimentary rock with a relatively high aluminium content. It is the world's main source of aluminium and gallium. Bauxite consists mostly of the aluminium minerals gibbsite (Al(OH)3), boehmite (γ-AlO(OH)) and diaspore (α-AlO(OH)), mixed with the two iron oxides goethite (FeO(OH)) and haematite (Fe2O3), the aluminium clay mineral kaolinite (Al2Si2O5(OH)) and small amounts of anatase (TiO2) and ilmenite (FeTiO3 or FeO.TiO2).

The Chemistry and Processing of Jamaican Bauxite

The Chemistry and Processing of Jamaican Bauxite The first commercial extraction of alumina (Al 2 O 3 ) from bauxite has been attributed to Henri Sainte-Claire Deville in about 1854. Soon after this, in 1888, Karl Joseph Bayer described what is now known as the Bayer Process, which led to a dramatic reduction in the cost of aluminum metal.
