  • Beneficiation of bauxite eprints@NML

    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%Nonmetallurgical bauxite ore is generally sold at higher prices, and consequently can offset lower recovery and higher beneficiation costs The primary objective of beneficiation for nonmetallurgical bauxite is to lower iron and titanium contents in the product, and also to enhance alumina valuesBauxite Beneficiation: An Approach to Value Addition in
