浮选—磁选联合工艺处理新疆某铜镍矿

以新疆某硫化铜镍矿为研究对象，采用铜优先浮选—铜优先浮选铜精矿磁选—铜优先浮选尾矿铜镍混合浮选联合流程，最终得到Cu品位25.43%、回收率52.08%、Ni品位0.19%、MgO含量2.32%的铜精矿和镍品位3.57%、镍回收率81.55%、含铜2.53%的铜镍混合精矿；全流程铜总回收率90.77%，镍总回收率82.10%。结果表明，该流程具有铜精矿品位高、镍损失率低、铜镍回收率高的优点。 

Treatment of a Copper Nickel Ore in Xinjiang by Flotation-Magnetic Separa-tion Combined Process

A copper nickel sulfide ore in Xinjiang is taken as the research object, the combined process of copper selective flotation-magnetic separation of copper concentrate-copper/nickel bulk flotation of tailings for selective flotation was adopted to finally obtain a copper concentrate with Cu grade of 25.43%, recovery of 52.08%, Ni grade of 0.19%, MgO content of 2.32% and a copper nickel mixed concentrate with nickel grade of 3.57%, recovery of 81.55% and copper content of 2.53%; The total recovery of copper and nickel in the whole process is 90.77% and 82.10%. The results show that the process has the advantages of high grade of copper concentrate, low nickel loss rate and high copper nickel recovery rate.
