新型铜钼分离抑制剂MX在某辉钼矿浮选中的试验研究

为了响应国家环保政策，选矿过程中不用、甚至少用氰化物，针对洛钼集团三道庄矿石在铜钼分离过程中使用氰化物作为抑制剂的问题，进行了新型铜钼分离抑制剂MX代替氰化物的试验研究。经过4次精选、2次精扫选、精1再磨的闭路工艺流程，在新型抑制剂MX用量为35 g/t的情况下，获得了品位为47.89%，回收率为84.23%的钼精矿，其中钼精矿中含铜0.09%，铜回收率仅为1.86%，浮选分离指标较好。试验最终实现了在铜钼分离过程中新型铜钼分离抑制剂MX代替氰化物的目标，减少了选矿药剂对环境的危害。

Experimental Study on a New Copper and Molybdenum Separation Depressant MX in a Molybdenite Floatation

In order to respond to the national environmental protection policy,no cyanide was used in the ore processing process,and a new type of copper-molybdenum separation inhibitor MX was used as an inhibitor during the separation of copper-molybdenum from the Sandaozhuang ores of China Molybdenum Co.,Ltd.Test study of cyanide replacement.After four cleaning,two fine scavenging,and concentrate 1 regrinding closed-circuit process,molybdenum concentrate with grade of 47.89% and recovery rate of 84.23% can be obtained with a new inhibitor MX dosage of 35g/t.The molybdenum concentrate contains 0.09% copper.The recovery rate of copper is only 1.86%,flotation separation index is well.In the process of copper-molybdenum separation,the new copper-molybdenum separation inhibitor MX replaces cyanide and reduces the harm of ore dressing to the environment.
