摘要
某矿石以黄铜矿、闪锌矿为主,针对该矿石的特征,采用优先浮选铜—再磨—精选铜—铜浮选尾矿选锌的工艺流程进行了选矿试验。在合理的药剂条件下,闭路试验得到了含Cu 18.45%、Zn 5.81%、Cu回收率71.54%的铜精矿和含Zn 50.95%、Zn回收率95.95%的锌精矿。
The main minerals in the copper- zinc were chalcopyrite and sphalerite. Mineral processing was carried out by a flowsheet of selective floatation copper and regrinding and cleaning copper and reconcentration zinc from copper flotation tailings. Under the rational reagent system, copper concentrate of 18.45% Cu with a recovery of 71.54%, and zinc concentrate of 50.95% Zn with a recovery of 95.95% were obtained in closed circuit experiment.
