Bauxite
Bauxite is usually classified according to its intended commercial application: abrasive, cement, chemical, metallurgical and refractory. Approximately 85% of the world's bauxite production is metallurgical bauxite and the alumina is extracted from the bauxite in a refinery using a wet chemical caustic soda leach
Advances in Beneficiation of Low-Grade Bauxite
Bauxite is the major alumina (Al 2 O 3) bearing ore used in the aluminum manufacturing industries.The bauxite containing less than 50% Al 2 O 3 is called low-grade bauxite ore which is commonly used for the alumina -based abrasives and refractories productions. The alumina -silica and alumina -ferrite complexes are the foremost impurities …
Beneficiation of bauxite
The silica present in the bauxite tends to be concen-trated in the finer grained fractions, and this charac-teristic makes bauxite amenable to beneficiation by screening techniques. Pearson' has reported that in a bauxite of average composition of 1.58% silica, the minus 100 mesh fraction analysed a silica content as high as 10.30%.
