Research on Potential Control Flotation of Molybdenite

In this paper, potential control flotation of molybdenite has been investigated which focus on the effect of pulp potential on flotation performance. Optimum flotation conditions of molybdenite are determined through tests: optimum pulp potential is 190mv~300mv, dosage of sodium sulfide is 6kg/t.The potential control flotation does not use sodium silicate which solved the problem of tailing ...
