在现场工艺流程试验的基础上，对某铜冶炼渣选矿工艺流程和条件进行了优化试验。在粗磨细度－0．045 mm粒级占75％、丁基黄药为捕收剂、Na2S为活化剂、中矿不再磨条件下，闭路流程试验获得的铜精矿品位为34．47％，回收率为92．61％。相比于现场工艺流程，可简化工艺流程，降低生产成本，提高浮选指标，增加总效益。

The processing flowsheet and parameters for concentrating a copper smelting slag were optimized. At a primary grinding fineness of -0.045 mm 75%, with butyl xanthate as the collector and Na2S as the activator, a closed?circuit flowsheet without the regrinding of middlings yielded a copper concentrate approaching 34. 47% Cu grade at 92. 61%recovery. Compared with the previous on?site processing technique, it is characterized with a simplified operation, reduced cost, improved flotation effect, as well as increased economic returns.
