Abstract: For the realization of the mineral processing wastewater recycling and zero emissions on a refractory copper and lead-zinc polymetallic sulfide ore in high altitude and environment vulnerable regions, on the basis of detailed study the complex copper and lead-zinc polymetallic sulphide ore process mineralogy, we used the process flow of copper-lead mixed floating, then separation of copper lead-zinc, floating zinc from the tailing of copper-lead, full recycling of the backwater was achived by using a combination of independent developed zinc mineral inhibitors ZG-2, and XZ-1 for separation of cop-per from lead and regent removing.Good indicators were obtained in the laboratory closed-circuit test with copper content of 23.77%, copper recovery rate 88.06%for the copper concentrate, and lead content of 77.18%, lead recovery rate 77.18%, and zinc content of 48.67%, zinc recovery rate 83.79%for lead concentrate for zinc concentrate.
