Experimental Study on Flotation of Low-grade Copper Ore in Tibet

Zhao Deng-kui

Abstract

Adopting a flowsheet consisting of a copper-sulfur bulk flotation,a bulk concentrate regrinding and a copper-sulfur separation,flotation technique was introduced to treat a low-grade copper ore from Tibet.In the closed-circuit test,a copper concentrate with a copper grade and recovery of 23.39% and 82.17%,respectively,and a sulfur concentrate with a sulfur grade and recovery of 36.58% and 61.97%,respectively,can be obtained.
