Investigation on Improving the Recovery of Molybdenum in Bulk Flotation of Mo-Copper Sulphide Ore

Abstract:

Improving the recovery of molybdenum is a research hotspot in the bulk flotation of Mo-copper sulphide ore. In this paper, the optimum flotation parameters for a kind of molybdenite ore obtained form Yunnan province, involving the grinding fineness, pulp concentration, dosages of kerosene and butyl xanthate, were determined in order to improve the recovery of Mo in the bulk Mo-copper flotation. In addition, a close-circuit flotation test was also conducted to simulate the practical process. A Mo-copper concentrate with Mo grade of 3.02% and recovery of 93.46% was obtained through the close-circuit flotation test, which satisfy the requirement for the bulk flotation of Mo-copper ore.
