Separation Test of Oxide Copper Ore in Yunnan

Abstract:

A task of a refractory oxide copper ore in Yunnan has been studied, the grade of copper is 2.76% in crude ore. This ore has high oxidation and deep combination, the oxidation ratio is 42.32% and the combination ratio is 33.01%, so it is difficult oxide copper. Because the sulfide copper in crude ore containing 21.27%, so by experimental research, we decided to adopt the process of floating copper sulfides, and then sulfide oxide copper. In the flotation of oxidized copper minerals, we take the process of desliming, the copper minerals have recycled efficiently, while making a small precious metal--silver has been associated enrichment. Through closed-circuit test, we obtained the final concentrate, which the grade of copper is 20.38%, the recovery of copper is 65.44% and the grade of silver is 80.15g/t.
