摘　　要：湖南某低品位铜镍矿现场铜镍混合精矿铜镍指标均较低。以原矿工艺矿物学研究结果和现场流程考查结果为基础,着重对矿石进行了磨矿细度、药剂制度和工艺流程优化研究,在对现场流程和药剂制度仅作较小改动的情况下,获得了铜品位为4.65%、镍品位为3.64%、铜回收率为86.48%、镍回收率为75.06%的铜镍混合精矿,与现场生产指标比较,在精矿质量指标略有提高的情况下,铜回收率提高了3.11个百分点,镍回收率提高了4.61个百分点。The recovery rate of copper-nickel mixed concentrate in a low-grade copper and nickel ore on-site of Hunan is low. On the basis of process mineralogical study and field test results, the paper focuses on researches the ore grinding fineness, reagent system and optimization of the flow-sheet process. Under less changing of on-site process and reagent re- gime, copper-nickel mixed concentrate with Cu grade and recovery of 4. 65% and 86. 48% , Ni grade and recovery of 3.64% and 75.06% were obtained. In comparison with the field production index, copper recovery rate is increased by 3.11 percentage point, nickel recovery rate is increased by 4. 61 percentage point with the concentrate quality improved slightly.
