  • BENEFICIATION STUDIES ON BAUXITE MINING WASTE:

    About 63 million tonnes of bauxite is being processed at National Aluminium Company Limited (NALCO), Damanjodi, Orissa, India, to produce around 157 million tonnes of alumina per year Owing to mechanized mining, selective mining of highgrade bauxite is not possible Hence, to mine 63 million tonnes of bauxite perThe 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%Beneficiation of bauxite [email protected] can get aluminum from bauxite beneficiation process, and the elements of residues in the process are iron oxide (10 – 30%), titanium dioxide (2 – 15%), silicon oxide (5 – 20%), and insoluble oxidation aluminum (020%)Bauxite Mining's Negative Effects on Human and
