According to ore properties of associated silver in lead-zinc sulfide ores,appropriate technological con-ditions and technological processes are used including the inhibitors combination of calcium oxide and calcium hypo-chlorite to depress pyrites,the combination of sodium carbonate and zinc sulphate to depress zinc mineral,ethyl thio carbamate,No.25 dithiophosphate collectors and ethyl xanthate mixed as combination collector to capture lead and sil-ver minerals,as well as selective separation of lead-zinc separation from lead tailings,achieving satisfactory technical indexes.Better results were obtained:the grade of Pb in lead concentrates is 45.18%,with the recovery of 88.98 %, silver grade in lead concentrates is 1 556.55 g/t,with the recovery of 73.55 %;Zn grade in zinc concentrates is 45.97 %,with the recovery of 83.77 %.
