COLUMN FLOTATION MODELLING AND TECHNOLOGY

An inherent limitation with the flotation of fine partcles in conventional cells is recovery of hydrophilic (gangue) particles by mechanical entrainment in the water reporting to the froth. The method of minimizing entrainment is to create a 5-3Ocm thick froth at the slurry surface. The froth permits the gangue to drain back to the pulp while

Abstract. This study explores the flotation behavior of chalcopyrite in the presence of different concentrations of sodium sulfide (Na 2 S·9H 2 O) at pH 12 under controlled potential conditions. It was observed that the flotation of chalcopyrite is not depressed completely when the pulp potential is low, even at high concentrations of sodium sulfide, i.e., 10 −1 –10 −2 mol/L.
