| 摘 要： | 某铜钼矿床是我国典型的超大型斑岩铜钼矿床,主要为原生硫化矿石,含铜0.47%、钼0.026%、硫2.02%,矿石品位低、性质复杂、难选。通过多种选矿工艺流程探讨,确定采用钼铜等可浮选再分离—铜硫混合浮选分离工艺流程产出钼精矿、铜精矿及硫精矿,实验室获得的闭路试验指标为:总铜精矿品位22.85%、铜回收率87.17%,钼精矿品位48.85%、钼回收率68.96%,硫精矿品位40.75%、硫回收率61.07%。

| Abstract: | Certain Cu-Mo ore in Tibet is typical of China's large porphyry copper-molybdenum deposit,which contains Cu 0.47%,Mo 0.026% and S 2.02% with the features of being low grade,complex and refractory.A detailed study has been carried out with the flowsheet of Cu-Mo iso-flotation-separation-Cu-S bulk flotation-separation.The results of the closed-circuit test show a copper concentrate with 22.85% copper and 87.17% copper recovery,a molybdenum concentrate with 48.85% molybdenum and 68.96% molybdenum recovery,a su... |
