江西某铜硫矿石含铜0．952％、含硫4．77％，为确定其合适的选矿工艺流程，以石灰为硫抑制剂，MA-1＋MOS 为组合捕收剂优先浮铜，选铜尾矿以硫酸为黄铁矿的活化剂，丁基黄药为捕收剂进行了选矿试验，实验室闭路试验获得了含铜21．37％、铜回收率为91．78％的铜精矿，含硫28．62％、硫回收率为62．15％的硫精矿，选矿指标较理想。
江西某銅硫礦石含銅0．952％、含硫4．77％，為確定其閤適的選礦工藝流程，以石灰為硫抑製劑，MA-1＋MOS 為組閤捕收劑優先浮銅，選銅尾礦以硫痠為黃鐵礦的活化劑，丁基黃藥為捕收劑進行瞭選礦試驗，實驗室閉路試驗穫得瞭含銅21．37％、銅迴收率為91．78％的銅精礦，含硫28．62％、硫迴收率為62．15％的硫精礦，選礦指標較理想。

There is 0.952% copper and 4.77% sulfur in a copper sulfide ore in Jiangxi Province. In order to find the proper mineral processing process for the ore,beneficiation experiments were conduc-ted using lime as sulfur inhibitor,MA-1 +MOS as combined collector for copper preferential flotation, sulfuric acid as pyrite activator and butyl xanthate as collector to deal with copper tailings for sulfur flota-tion.Copper concentrate with 21.37% Cu and recovery of 91.78%,sulfur concentrate with 28.62% S and recovery of 62.15% is obtained,thus the process indexes is ideal.
