摘　　要：为从铜山深部矿石含铜硫化矿中分选铜,在系统的工艺矿物学研究和选矿工艺研究的基础上,确定采用铜硫混浮—铜硫分离—中矿再磨再选—尾矿磁选选铁工艺流程,最终获得了铜品位为15.50%、含硫34.17%、含铁33.16%、铜回收率为86.90%的铜精矿,硫品位为41.27%、含铜0.236%、含铁39.63%、硫回收率为74.68%的硫精矿;铁品位为63.22%、含铜0.042%、含硫0.60%、铁回收率为38.48%的铁精矿。In order to separate copper from a copper-bearing sulfide ore of Tongshan deep ore,copper-sulfur bulk flotation,copper and sulfur separation,regrinding and reconcentration of middlings,iron enrich of tailings by magnetic separation process is selected based on systemic process mineralogical research and beneficiation process research. Copper concentrate with 15. 50% copper,34. 17% sulfur,33. 16% iron and copper recovery of 86. 90%,sulfur concentrate with 41. 27% sulfur,0. 236% copper,39. 63% iron and sulfur recovery of 74. 68%,iron concentrate with 63. 22% iron,0. 042% copper,0. 60% sulfur and iron recovery of 38. 48% are finally obtained.
