Research on Mineral Processing for a Polymetallic Sulphide Ore

The raw ore of a polymetallic complex sulphide ore contains 0.71%Cu,3.08%Pb,1.43%Zn and 15.57%S with properties of low grade,fine dissemination,close symbiosis relationship and easy flotation but difficult separation of sulphide.Through contrastive experiments of several technological flowsheets and reagents,the technological flowsheet of bulk flotation followed by separation flotation was determined,that is,first flotation of the mixed concentrate of Cu,Pb,Zn and S,then selective floatation of Cu-Pb,separa...
