摘　　要：内蒙古某铜钼矿属于低品位大型斑岩铜钼矿,矿石主要有用矿物为黄铜矿、斑铜矿、蓝辉铜矿、铜蓝和辉钼矿。现场工业生产中铜钼回收采用铜钼混合优先(对黄铁矿)流程,流程相对简单。随着矿石性质的不断变化,原有药剂制度对现有矿石适应性变差,铜钼回收率目前均有不同程度的下降。为了提高铜和钼的回收率,进行了药剂制度优化试验。药剂制度优化后采用捕收剂BK925代替原有捕收剂,可实现铜钼的高效回收,铜钼回收率均可在87%以上。A copper and molybdenum mine in Inner Mongolia belongs to a low-grade large-scale porphyry copper-molybdenite mine,and main useful minerals of the ore are chalcopyrite,bornite,chalcocite,cyanite and molybdenite.The copper-molybdenum mixed priority(for pyrite)process is adopted in the recovery of copper and molybdenum in the field industrial production,and the process is relatively simple.With the continuous change of ore properties,the adaptability of the original reagent system to the existing ore has become worse.The recovery of copper and molybdenum has decreased in different degrees at present.In order to improve the recovery of copper and molybdenum,the optimization test of the reagent system is carried out.After the optimization of the reagent system,the collector BK925 is used instead of the original collector,which can realize the efficient recovery of copper molybdenum,and the recovery of copper molybdenum is over 87%.
