2020 9 1At pH 10, the bornite recovery remained unchanged even though NS was added as shown in Fig. 14. For chalcopyrite, NS addition did not change or decrease the flotation recovery at pH 8 and 9 but 50 g/t of NS addition increased the recovery at pH 10. These trends could be supported by the zeta potential measurements and solution analyses.

PGMs. Flotation depends on a number of factors which include particle size, pulp density, reagent dosage and pH. In practice, selectivity in complex separation is dependent on a balance between reagent dosages and pH [1]. Thus reagents and pH should be delicately balanced to achieve optimum recoveries and grade. Previous studies on the

Abstract: In this paper, the effect of sodium butyl xanthate (NaBX) adsorption on the surface of bornite at different pH on flotation was studied by adsorption kinetic and thermodynamic. The flotation results demonstrated that the recovery was the highest when pH was 9 in NaBX solution (410-5 mol/L). The adsorption kinetics showed the reaction of NaBX on the bornite
