摘　　要：为有效降低钼精矿产品中铜含量和减少氰化钠的用量,以降低生产成本、减少环境污染,进行了钼精扫选浮选柱底流局部开路分流的工艺改造。生产实践表明,改造后钼精矿产品中铜含量均小于0.4%,完全达到合格产品的要求(≤0.5%),且氰化钠抑制剂用量也由原来的60g/t降低到30g/t。The purpose of this study is to reduce the content of copper and to cut down the dosage of inhibitors such as sodium cyanide in concentrate products of molybdenum in order to decrease the production cost and reduce the environmental pollution.This paper reconstructs the process of local open shunt at bottom flow of refined scavenging flotation column.The production practice shows that the contents of copper in refined mineral products are all lower than 0.4%,which meets the requirements（≤0.5%） perfectly,and the dosage of inhibitors decreases from 60g/d to 30g/d.
