【摘要】 为了充分利用矿产资源,并提高企业效益,进行了提高某原生钨细泥中黑钨矿选别指标的技术研究。经过大量的试验,最终确定采用强磁选预富集,磁选粗精矿分级进行摇床回收钨的工艺流程。原矿品位0.45%,全流程闭路试验指标为:钨精矿的产率为1.41%,WO3品位为25.50%,WO3回收率为79.90%。更多还原

【Abstract】 In order to make full use of mineral resources and improve enterprise benefit, the technical research of improving the separation index of fine slimes of primary tungsten was carried out. Through conditional tests, the pre-concentration by strong magnetic separation was determined, and the rough concentrate of magnetic separation was treated by classification followed by shaking table separation to recover the tungsten minerals. The closed-circuit test results showed that the yield of concentrate was 1.41%,and the grade and recovery of WO3 was 25.50% and 79.90% respectively.更多还原
