摘要
国外某低品位含金硫化铜矿石含铜0.36%、金0.08 g/t,针对该金、铜矿物嵌布粒度细,且主要与黄铁矿致密共生的性质特点,采用了"全硫混浮—混合粗精矿再磨—铜硫分离"的选矿工艺流程。闭路试验获得铜精矿含铜24.65%、含金4.21 g/t,铜回收率为90.19%、金回收率为68.24%,以及硫精矿含硫45.97%、硫回收率68.96%的良好试验指标,实现了铜、金资源的高效回收。
A low-grade sulfide copper with gold contains 0.36% Cu and 0.08 g/t Au. The processing flowsheet of “all sulfide mineral mixed flotation-mixed coarse concentrate regrinding-copper and sulfur separating” was made to suit this raw ore in which the Cu-Au ore has inlaid granularity fine and is closely dense symbiosis with pyrite. Through the closed circle test, the copper concentrate with 24.65% Cu and Gold 4.21 g/t, which the copper and gold recovery is 90.19 % and 68.24% respectively, the sulfurconcentrate containing 45.97% S with recovery 68.96 % were obtained. The copper and gold resources were effectively recovered by the process used in the test.
