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%.

THE ALUMINIUM STORY BAUXITE TO ALUMINA: THE …

The ultimate product of calcination is the most stable phase of alumina, corundum or -alumina. This is, however, not desirable for smelting, because -alumina is slow to dissolve in the bath (refer to Section 24). For the formation of Smelting Grade Alumina (SGA), calcination is carried out at around 950°C.
