【摘要】 云南河口铜矿石含Cu 0.59%、S 4.57%、Fe 26.98%,属伴生硫铁的低品位硫化铜矿石,铜、硫、铁在矿石中分别主要以黄铜矿、黄铁矿、磁铁矿形式存在,但有少部分黄铜矿与黄铁矿形成固熔体。采用铜硫混合浮选—铜硫分离浮选—浮选尾矿弱磁选工艺对该矿石进行综合回收铜、硫、铁的选矿试验,得到了铜品位为18.03%、铜回收率为93.07%的铜精矿,硫品位为52.02%、硫回收率为56.34%的硫精矿和铁品位为61.90%、铁回收率为27.38%的铁精矿,从而为该矿石的合理开发利用提供了技术依据。更多还原

【Abstract】 Hekou copper ore in Yunnan contains Cu grade of 0. 59%,S grade of 4. 57% and Fe grade of 26. 98%. It belongs to the S-Fe associated low grade copper sulphide ore,among which Cu,S and Fe exist in the form of chalcopyrite,pyrite and magnetite respectively. But there are a small amount of chalcopyrite and pyrite formed solid solution. Comprehensive recovery tests of copper,sulfur and iron were conducted by the process of copper-sulfur bulk flotation,copper-sulfur separated flotation,and low intensity magnetic separation of flotation tailings. Then,copper concentrate with Cu grade of 18. 03% and Cu recovery of 93. 07%,sulfur concentrate with S grade of 52. 02% and S recovery of 52. 02%,and iron concentrate with Fe grade of 61. 90% and Fe recovery of 27. 38% were obtained separately. This provides a technical basis for development and utilization of the ore.更多还原
