Abstract

For a Cu-Pb-Zn complex multi-metal ore,the principle flowsheet is adopted by floating sulfide minerals followed by of oxide minerals.The process ofcopper-lead minerals bulk flotation-separation of copper and lead minerals-zinc flotation-oxide lead flotation is determined.Good indexes are obtained by closed-circuit tests.The final sulfide concentrates grading 19.51% Cu,59.39% Pb,40.98% Zn are obtained,at recoveries of 66.72% Cu,54.48% Pb and 64.29% Zn.The oxide concentrate grading 44.78% Pb is also obtained at recovery of 21.22% Pb.The separation of valuable minerals of copper,lead and zinc can be achieved.
