It is difficult to flotation separation of some Ag polymetallic ore because there are many different kinds of metallic sulfide minerals and the ore properties is very complex.In order to solve these problems，the identification of technological mineralogy and mineral processing experiments were conducted in the paper.By closed circuit tests，the copper concentrate which with the Cu grade of 27.22% and recovery rate of 85.29% could be obtained，as well as the lead concentrate which with the Pb grade of 56.37% and recovery of was 85.02%.The total Ag recovery rate of them was 86.73%.The zinc concentrate which with the Zn grade of 53.22% and recovery rate of 77.48% was also gotten.Compared with the mineral processing practice，the technology in the paper is not only with concise flowsheet and simple reagent system，but also bringing better concentrate grade and recovery rate of Cu，Pb，Ag.
