在硫化铜镍矿石选矿时,为了提高贵金(尸专)的回收率,常采用磁选方法从混合浮选尾矿中分离出一卩分磁精矿。除铂族金(尸专)外,在磁精矿中还含有将近2%的有色金(尸专),约50%Fe和约20%S。若在企业的镍系统中直接处理这种磁精矿,则由于在这种产品中存在大(旦力)的铁,必然导致金(尸专)损失的增加。因此,在单独的冶炼工序里脱除磁精矿中的卩分铁和硫,并把有色金 In copper sulphide nickel ore beneficiation, in order to improve the recovery of precious gold (corporeal), magnetic separation method is often used to separate a magnetic separation concentrate from mixed flotation tailings. In addition to the PGMs, nearly 2% of the non-ferrous (Mg), about 50% Fe and about 20% S are also contained in the magnetic concentrate. If this concentrate is treated directly in the nickel system of an enterprise, the presence of large (denser) iron in such a product will inevitably lead to an increase in the loss of gold. Therefore, in a separate smelting process to remove the magnetic separation of iron and sulfur Jie, and the non-ferrous
