摘要/Abstract

摘要： 内蒙古某低品位斑岩型铜钼矿选矿厂以酯105+煤油为捕收剂进行铜钼混合浮选，不仅分选指标不太理想，而且煤油采购越来越困难,价格也越来越高，严重影响了正常生产和经济效益的提高。为解决生产中面临的这些问题，采用从美国引进的新型高效捕收剂替代原浮选药剂对该矿石进行了选矿试验。结果表明：以MO+CO-47为铜钼混浮捕收剂，在工艺流程不变的情况下，获得了铜、钼品位分别为1970%、0339%，铜、钼回收率分别为9264%、8034%的铜钼混合精矿，与现场生产指标相比，精矿铜、钼品位分别提高145、0009个百分点，回收率分别提高706、1005个百分点。因此，用MO+CO-47替代原捕收剂酯105+煤油可以取得理想的降本增效效果。

Abstract: The dressing plant of a low-grade porphyry copper molybdenum in Inner Mongolia adopts kerosene as collector of molybdenum minerals to make the copper molybdenum mixed flotation But the flotation indexes are not ideal，and the kerosene procurement is extremely difficult and the price is high，which seriously affected the production and the improvement of economic benefits To solve these problems in production，a new American collector is adopted to replace the original flotation reagents for mineral processing conditions research The results show that with MO+CO-47 as collector of Cu-Mo mixed flotation，Cu-Mo concentrate with Cu and Mo grade of 1970% and 0339%，and Cu and Mo recovery of 8602% and 7690% were obtained separately by the same process above Compared with the on-site result，Cu and Mo grade is increased by 145 percentage point and 0009 percentage point and the Cu and Mo recovery is increased by 706 percentage point and 1005 percentage point respectively Hence，the desired effect of cost reduction and high efficiency can be realized by adopting MO+CO-47 instead of the original collector 105+ kerosene.
