beneficiation of payas iron ore containing bauxite

Beneficiation of bauxite

ctive only for the ore containing 4 to 5 reactive silica, in the light of the criteria enumerated above. Beneficiation of bauxite containing less than 4-5% silica was not found to be justifiable especially in view of the depletion of ore reserves. A typical economic analysis for bauxite containing 4'43°, reactive silica is summarised in Table Ill.
