摘　　要：某铜硫矿中含Cu 0.55%,含S 5.21%,磁黄铁矿含量较高.在对其进行工艺矿物学研究的基础上,将矿石磨至粒径小于0.074 mm占65%,采用"快速浮选-混合浮选-混合粗精矿再磨"工艺进行试验,结果表明,最终可获得含铜20.84%,回收率为93.97%的铜精矿.相比现场工艺提高了选铜指标,并节约了磨矿成本.A copper sulfide ore contains 0.55 % of Cu and 5.21 % of S with very high content of pyrrhotite. On the basis of the process mineralogical study, grinding fineness of 65 % of minerals particle size is less than0.074 mm. The process of ＂flash flotation-mixed flotation-mixed rougher concentrate regrinding ＂ is adopted.The results show that copper concentrate with copper bearing of 20.84 % and recovery rate of 93.97 % can be obtained. Compared with field process,the sorting index of copper is improved to save the grinding cost.
