  • Beneficiation of bauxite Welcome to [email protected]

    The silica present in the bauxite tends to be concentrated in the finer grained fractions, and this characteristic makes bauxite amenable to beneficiation by screening techniques Pearson' has reported that in a bauxite of average composition of 158% silica, the minus 100 mesh fraction analysed a silica content as high as 1030%
