Abstract: Beneficiation test of mixed copper ore in Yunnan was done. The results show that the ore by closed-circuit flotation process of a crude,two fine and two sweeps,the copper concentrate grade is20. 96 %,the copper recovery is 86.97 %,the silver grade is 406.09g∕t. and the silver recovery rate is 63. 62%. Objective elements have been recycled.

Key words: mixed copper, silver, flotation
