摘　　要：通过对两批矿样不同种类捕收剂对比试验,证明捕收剂WS能大幅度提高铜精矿品位。试验发现,即使采用相同的药剂制度,矿石性质的改变对选别指标影响也很大。WS能很好地适应矿石性质改变,即使是被Cu2＋活化的黄铁矿,也不能被它大量捕收。所以在矿石性质改变时使用WS作铜捕收剂,铜精矿品位也能始终保持在20%以上。采用WS作捕收剂,混合闭路最终试验结果铜、钼品位分别为23.89%~25.91%、0.890%~1.804%,铜、钼回收率分别为90.60%~94.79%、84.34%~88.40%。It was proved that the grade of Cu concentrator could be increased substantially using WS as the collector,through comparative tests using different kinds of collector for two groups of the core sample.It was found that even using the same regime of agent,the result was obviously affected by the characteristic variation of the ore.However,WS can effectively adapt to this variation,and has outstandingly selective,even for the pyrite activated by Cu2＋.Hence when the character of the ore changes,the Cu contractor grade could also reach over 20% using WS as the collector of Cu.In the final closed cricuit experiment,the grade of Cu,Mo was around 23.89%~25.91% and 0.890%~1.804%,respectively,and the recovery of Cu,Mo around 90.60%~94.79% and 84.34%~88.40%,respectively.
