某低品位铜镍矿选矿试验研究

某低品位硫化铜镍矿含镍0.63%、含铜0.62%,脉石矿物主要以橄榄石、蛇纹石、绿泥石、辉石等含镁矿物为主。根据矿石性质,对其进行了浮选试验研究,采用现场生产工艺流程,通过试验调整、优化工艺参数后得到了镍品位6.11%、回收率72.30%和铜品位7.06%,回收率78.61%的合格精矿,提高了资源利用率,为矿山可持续发展提供了合理的途径。

Experimental Study on Mineral Processing of Low-grade Cu-Ni Ore

A low-grade copper-nickel sulfide ore contains nickel 0.63 %,copper 0.62 %,and there are a lot of magnesium oxide minerals in the gangue minerals,including olivine,serpentine,chlorite,pyroxene,etc.According to mineral characters,the flotation test of the ore is studied.By experimenting,regulating and optimizing the technical parameter,we use the site production process and gets the qualified concentrate： nickel grade was 6.11 %,nickel recovery rate reaches 72.03 %,and copper grade was 7.06 %,copper recovery rate reaches 78.61 %.That not only improves resource utilization,but also provides a reasonable way for sustainable development of mineral enterprise.
