The microstructure of bauxite determines to a significant extent the opportunities for its beneficiation and optimum processing downstream. Adequate fine grinding commensurate with its microstructure may result in proper mineral liberation and grain size distribution required for effective ore dressing (i.e. H/M or magnetic separation) and digestion respectively.

The most widely used chemical process of refining bauxite into alumina, the Bayer process, involves dissolving the Al2O3 out of the bauxite rock with caustic soda (NaOH) at elevated temperature and pressure. The Al2O3 fraction of the bauxite is dissolved into solution, to later be precipitated out as alumina. However, a high-grade bauxite contains up to 60% Al2O3, and many operating bauxite

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. Beneficiating ore also reduces the amount of material that needs to

Looking into the different low-grade bauxite ores still prevailing in different parts of India it can be concluded that, mineralogical and chemical characteristics of the ore samples are a pre-requisite step before proceeding for beneficiation. Hence, a detail mineralogical, geochemical and mineral chemistry of a typical bauxite ore of Central India was undertaken for detail characterisation

AGB2A, a Guinea based company, produces one of the best metallurgical grade bauxite for alumina refinery by dry beneficiation process involving crushing and screening of ore. GBT bauxite is unique and different from usual Guinea bauxite as these are embedded in the silica rich fines at the periphery of hillocks. This is the first project in Guinea to beneficiate bauxite ore at the mine site
