Research on Flotation Test for Yunnan Copper Ore

JI Yun-bo

Abstract

The property of the copper ore was analyzed, and a series of tests on copper-sulphur mixed flotation and copper-sulphur flotation separation were conducted, besides, the scheme of closed-circuit test for flotation has worked out on this basis. The high-quality copper concentrates with a copper grade of 23.56%, a copper recovery of 95.24% and a silver grade of 190.1g/t have been obtained by the tests.
