云南某铜钼矿浮选药剂制度优化研究

Optimization of flotation reagent system for a copper-molybdenum ore in Yunnan province

在保持原有铜钼混合浮选-铜钼分离浮选工艺的基础上,采用多种新型捕收剂、抑制剂分别对云南某斑岩型铜钼矿混合浮选、铜钼分离浮选进行了药剂优化试验研究,最终选用捕收剂W3和W4、起泡剂F-425和MIBC、高效的铜抑制剂M8等,并进行全流程闭路试验,获得了钼品位44.92%、钼回收率80.57%的钼精矿,铜品位25.03%、铜回收率91.10%的铜精矿。与设计流程浮选指标相比,铜回收率提高了回收率提高了4.10个百分点,钼的回收率提高了4.57个百分点。

Without changing the original copper-molybdenum mixed flotation and copper-molybdenum separation process,a variety of new collectors and inhibitors are used to study the reagent system optimization for a copper-molybdenum mixed flotation and copper-molybdenum separation flotation for a porphyry copper-molybdenum in Yunnan province.The effects of W3 and W4,foaming agent F-425 and MIBC and high-efficiency copper inhibitor M8 are obtained.Ultimately,according to the results of the locked-cycle test,the grade of the molybdenum concentrate comes to 44.92% with a Mo-recovery of80.57%;the grade of the copper concentrate comes to 25.03% with a Cu-recovery of 91.10%.Compared with the flotation index of the design process,the recovery of copper was increased by 4.10 percentage points,and the recovery of molybdenum was increased by 4.57 percentage points.
