摘    要:吉林某难选铜镍硫化矿石铜品位为0.19%、镍品位为0.42%。矿石中铜镍矿物共生密切,嵌布粒度微细。为给该矿石的开发利用提供依据,进行了铜镍混合浮选-分离浮选试验。结果表明:在磨矿细度为 -0.074 mm占80%条件下,以硫酸铜为活化剂、乙基黄药+丁铵黑药为捕收剂、2号油为起泡剂、CMC为精选抑制剂,经1粗3精2扫铜镍混合浮选获得铜镍混合精矿,铜镍混合精矿再磨至-0.038 mm占90%,以石灰为抑制剂、乙基黄药为捕收剂,经1粗3精2扫铜镍分离浮选,获得了铜品位为24.62%、铜回收率为79.04%、镍品位为0.73%、镍回收率为1.06%的铜精矿及镍品位为5.73%、镍回收率为75.85%、铜品位为0.11%、铜回收率为3.22%的镍精矿,实现了铜镍的有效综合回收。

关 键 词:铜镍硫化矿  混合浮选  浮选  分离

Abstract:There is 0.19% copper and 0.42% nickel in a refractory copper-nickel sulfide ore from Jilin.Copper and nickel ore mineral paragenesis significantly,fine disseminated.To provide technique basis for the development and utilization of the ore,copper and nickel bulk flotation-copper and nickel separation flotation process was conducted.The results show:at the grinding fineness of -0.074 mm accounted for 80%,using copper sulfate as activator,ethyl xanthenes + butyl ammonium aeroflot as collector,2# oil as the foaming agent,CMC for selection inhibitors via one roughing-three cleaning-two scavenging for copper and nickel bulk flotation to achieve Cu-Ni bulk concentrate,reground the Cu-Ni bulk concentrate to -0.038 mm accounted for 90%,with lime as inhibitor,ethyl xanthate as collector endure one roughing-three cleaning-two scavenging copper and nickel separation flotation,copper concentrate with copper grade of 24.62%,copper recovery of 79.04%,nickel grade of 0.73%,nickel recovery of 1.06% of the,nickel concentrate with nickel grade of 5.73%,nickel recovery of 5.73%,copper grade of 0.11%,copper recovery of 3.22% was achieved.Comprehensive recovery of the copper and nickel was realized.
Keywords:Copper-nickel sulphide ore  Bulk flotation  Flotation  Separation
