摘　　要：对新疆某铜镍矿山低品位高泥高镁硫化铜镍矿进行了浮选试验研究。以羧甲基纤维素钠和水玻璃为组合抑制剂、以丁基黄药和丁铵黑药为组合捕收剂,采用铜镍混合浮选-铜镍分离工艺流程,闭路试验可获得铜品位25.11%、铜回收率79.90%、含氧化镁2.02%的铜精矿以及镍品位6.98%、镍回收率75.01%、含氧化镁5.32%的镍精矿,实现了铜、镍的高效回收和有效分离。Flotation tests were conducted for a low⁃grade copper⁃nickel sulfide ore with high content of mud and magnesium oxide from Xinjiang.Using sodium carboxymethyl cellulose and sodium silicate as a combined inhibitor,butyl xanthoxanthate and butyl ammonium black as a combined collector,a closed⁃circuit test with a flowsheet consisting of a Cu⁃Ni bulk flotation and a Cu/Ni separation produced a copper concentrate grading 25.11%Cu at 79.90%recovery,with MgO content of 2.02%,as well as a nickel concentrate grading 6.98%Ni at 75.01%recovery,with MgO content of 5.32%.It is concluded that effective recovery and separation of copper and nickel can be actualized.
