Experimental Research on Synchronous Flotation of Copper and Silver in a Silver-bearing Copper Oxide Ore with High Carbonate Gangue from Yunnan

A synchronous flotation test of copper and silver in a silver-bearing copper oxide ore with high carbonate gangue from Yunnan was studied. The results show that copper and silver concentrate copper grade of 22.03% and recovery of 71.69% was achieved through the closed circuit flotation test. And the grade and recovery of silver in copper concentrate were relatively 1095 g/t and 81.90%. The synchronous flotation technology using in the silver-bearing copper oxide ore is effectual .
