摘要
以内蒙古某铜铅锌复杂多金属硫化矿为研究对象,在对该矿石工艺矿物学研究的基础上,进行了大量的探索试验研究。最终采用先磁选除铁—铜铅混合浮选—铜铅分离—铜铅尾矿选锌的工艺流程,以及应用新型高效铜铅捕收剂QF-11、抑制剂CMC等,获得了含铁49.42%、回收率为56.93%的磁精矿,含铜21.12%、回收率75.49%的铜精矿,含铅48.29%、回收率79.23%的铅精矿,含锌46.73%、回收率86.30%的锌精矿,银综合回收率76.60%,实现了对该矿石综合利用的目的。
The mineral process of a copper-lead-zinc complex polymetallic sulfide ore in Inner Mongolia is studied. Based on process mineralogy study, the experimental study of a great deal exploration. The flowsheet is removal of iron by magnetic, copper-lead bulk flotation, separation of copper and lead from the bulk rough concentrates and flotation of zinc from the copper-lead tailings is determined with the new efficient copper-lead collector QF-11 （ The main ent is isopropyl ethyl xanthate）, inhibitor CMC and etc. The magnetic concentrate containing iron 49. 42%, iron recovery 56. 93%. copper concentrate containing 21.12%, copper recovery 75.49%. lead concentrate containing lead 48.29%, lead recovery 79.23%. zinc concentrate containing zinc 46. 73% ,zinc recovery 86. 30%. and the copper-lead concentrate has been obtained silver recovery 76.60%. which has successfully realized the mine resources comprehensive utilization goal.
