摘要
为解决铜钼分离浮选后钼精矿中铜含量较高的问题,以河南某选厂钼精矿为研究对象,采用超导磁选方法进行细粒黄铜矿分离试验研究,重点对脉动冲次、分散剂用量、背景磁场强度及聚磁介质直径进行了试验优化,取得理想的分选指标。最终确定采用"分级—细粒级超导磁选"工艺,原钼精矿中铜含量由0.69%降至0.193%,磁选精矿产率为93.16%,钼的总回收率为95.96%。
In order to solve the problem of high copper content in molybdenum concentrate after flotation separation,taking molybdenum concentrate from a dressing plant in Henan Province as an object,fine chalcopyrite was separated from molybdenum concentrate by a superconducting magnetic separator. Through optimizing pulsating rate,dispersant dosage,background magnetic field strength and Collecting medium diameter,the optimal separation result was obtained. Finally,＂classification-superconducting magnetic separation of fine size fractio＂was finally adopted. The copper content in molybdenum concentrate decreased by from 0. 69% to 0. 193%,with the concentrate yield of 93. 16% and the Mo recovery of 95. 96%.
