摘　　要：某新探明铜硫铁矿石有用矿物为铜矿物、硫矿物和铁矿物,回收矿物种类较多,磁黄铁矿含量较高,矿石性质复杂,为了综合回收该矿石中的铜硫铁矿物,进行了新工艺试验研究。对该矿石进行优先浮选分别回收铜和硫,弱磁选—强磁选回收铁的新工艺试验研究,综合回收铜硫铁,获得铜精矿品位19.53%,回收率38.58%;硫精矿品位43.27%,回收率91.90%;铁精矿品位64.72%,回收率56.60%的较好指标。新工艺试验为该矿石综合回收铜硫铁提供了研究基础。It is difficult to recover useful minerals from a newly-found multi-metal ore bearing copper, sulfur and iron because of its higher content of pyrrhotite and complicated properties. In order to recover copper, sulfur and iron comprehensively, the experimental study on new beneficiation technology was conducted. Copper and sulfur was recovered respectively by flotation in priority and iron was recovered with low-intensity magnetic separation and high-intensity magnetic separation. The grade and recovery of copper, sulfur and iron concentrate were 19.53% and 38.58%, 43.27% and 91.90%, 64.72% and 56.60%. The experiment provided study foundation for recovering copper, sulfur and iron comprehensively.
