Dec 15, 2015 Bauxite is the most important raw material for production of aluminium metal and in the manufacture of abrasives, ceramics and refractories. Depending on the end use of the mined bauxite ores, appropriate prebeneficiation need to be adapted for removal of impurities such as calcium, iron oxides and silica.
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.
