Study on the pilot test of copper-lead-zinc skarn sulphides in Baoshan Yunnan

In the present paper flotation research on skarn-type Cu-Pb-Zn associated mine in Baoshan Yunnan was carried out during pilot test and obtained much better flotation index. Then copper concentrate with Cu grade of 18.57% at an 78.04% recovery, lead concentrate with Pb grade of 67.37% at an 58.26% recovery and zinc concentrate with Zn grade of 49.11% at an 88.57% recovery are obtained respectively. A refined beneficiation test indicator had been obtained, which provides a basis for reasonably recovering these mineral resources.
