摘　　要：针对某硫化铜镍矿石磁黄铁矿含量高、铜镍品位低、嵌布粒度细的实际,自主研发了适应该矿物浮选的高效选择性组合抑制剂及"铜镍硫混浮-精矿分离硫"新工艺。新药剂和新工艺闭路试验获得了铜品位2.69%、镍品位7.54%、铜回收率77.52%、镍回收率77.87%的铜镍混合精矿,硫精矿硫品位34.25%。To process a refractory pyrrhotite-rich copper-nickel sulfide ore with low content of copper and nickel and fine dissemination size of valuable minerals,a new type of high-efficient depressant for pyrrhotite mineral was developed and a novel technology of copper-nickel-sulfur mixed flotation and Ni-S flotation separation was proposed. The closed-circuit test on this new flowsheet with new depressant produced a copper-nickel bulk concentrate assaying 2. 69% Cu and7. 54% Ni with a copper recovery of 77. 52% and a nickel recovery of 77. 87%,as well as a sulphur concentrate grading 34. 25% S.
