Xiaobo Li, Xia Guojin, YU Xia-jing, Tingsheng Qiu

Abstract

A complicated copper-iron sulfide ore containing copper and sulfur content of 0.39% and 36.19%,respectively in Anhui Province was investigated.Under low basicity conditions,using a combined collector of BK-301 and LP-01(ratio 2∶4),and following a Cu/S separation flowsheet consisting of a selective flotation of copper and a flotation of inactivated sulfides from the original slurry,a copper concentrate with a copper grade and recovery of 18.46% and 72.16%,respectively,and a sulphur concentrate with a sulfur grade and recovery of 48.14% and 93.72%,respectively,were obtained.
