Comprehensive Recovery Test Research on Complex Copper-Lead-Zinc Ore in Xinjiang

In view of the low grade,fine dissemination,high secondary copper content,density symbiosis and partial oxidation features of the complex copper-lead-zinc ore,the authors adopted copper-lead mix-flotation,copper-lead separation and collection flotation zinc from tailings of mixed float.Under appropriate grinding fineness,new inhibitors T8 and ZnSO4 at ratio of 1to 2 are used to suppress zinc,new collector ester-12 used for copper-lead flotation and new depreeant T81 for suppress of lead content.Indicators achived in closed-circuit test are as follows: copper concentrate containing copper 25.24%,the copper recovery 56.61%;Lead concentrate containing lead 59.82%,lead recovery 80.62%;Zinc concentrate containing zinc56.55%,zinc recovery 77.99%,which has successfully realized the mine resources comprehensive recovery goal.
