Beneficiation of bauxite - EPrints

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%.
