【摘要】 阿舍勒选矿厂自投料试车以来,尽管生产指标稳步上升,但由于建厂时一些技术设施不到位,铜回收率一直处于较低水平。为了进一步提高铜回收率,在现有条件下,通过对铜锌混合浮选工艺流程进行铜部分优先浮选+混浮的技术改造,以及在混浮中使用高效捕收剂PAC与黄药混合加药,使铜回收率由78．68％提高到84．34％。更多还原

【Abstract】 Although the index of production has been normally improved in Ashele Separating Plant after commercial-scale trial, the recovery of copper is always low because the shortage of technical equipment during the construction. Now, in order to improve the recovery of copper, by technical reforming of partial copper priority separation with mixed flotation for the technical flowsheet of copper-zinc mixed flotation, and the mixed using of high effective collector PAC and xanthate during mixed flotation, the recovery of copper is improved from 78.68% to 84.34%.更多还原
