Abstract

An experimental research on flotation technology for separating a Copper,Lead and Zinc polymetallic sulphide ore in Gansu was performed.The flowsheet is removal of carbon by reverse flotation,copper-lead bulk flotation,separation of copper and lead from the bulk rough concentrates and flotation of zinc and sulfur from the copper-lead tailings.Cu concentrate containing 14.32% Cu,Pb concentrate 45.60% Pb,Zn concentrate 47.45% Zn and S concentrate S 31.26% were obtained,with a recovery of 37.68%,83.21%,92.71% and 26.52% respectively.Comprehensive utilization were realized.
