摘要: 福建某铜矿石有用矿物有硫化铜和黄铁矿。对该矿石进行了优先浮铜工艺技术条件研究,结果表明,采用2粗4扫、粗精矿合并1次精选、中矿顺序返回流程处理,最终获得了铜品位为22.44%、铜回收率为90.23%的铜精矿,铜精矿硫回收率仅为17.58%,为铜尾矿选硫取得较高硫回收率创造了条件。

Abstract: The useful minerals in a copper ore of Fujian consist of copper sulfide and pyrite. The conditioning tests on the preferential copper floatation are studied. The results show that final copper concentrate with Cu grade of 22.44% and Cu recovery of 90.23% was obtained by the process of two-roughing,four-scavenging,one-cleaning with rough concentrate and middles back to the flow-sheet in turn. S recovery in copper concentrate was only 17.58%,which creates the conditions for higher sulfur recovery from copper tailings.

Key words: Copper ore, Copper sulfide, Pyrite, Preferential copper floating
