| Abstract: | This article introduces the ore property of a low-grade porphyry copper sulphide ore in Yunnan province,and mades the beneficiation process according to the embedded features of the valuable mineral.Through experiment contrast and optimization,under the grinding fineness -0.075mm92%, the recommended selective flotation process closed-circuit flowsheet can obtain copper concentrate with a yield of 1.99%,copper20.97%,gold 12.18g/t,copper recovery of 92.35%,gold recovery of 73.87,and sulphur concentrate with a yield of 2.58%,sulphur46.16%,sulphur recovery of 60.77%.This process efficient comprehensive recovery of valuable elements in the ore. |
