摘　　要：某黑钨矿由于成分较为复杂,致使细泥段WO3回收率较低,为了进一步回收该尾矿中的钨,开展了试验研究工作。试验研究确定了筛分—离心选矿机粗选—悬振锥面选矿机精选流程,可从WO3含量0.142%的尾矿中获得WO3含量28.04%、WO3回收率49.20%的黑钨精矿。Because of the complex composition of wolframite raw ore,the recovery rate of WO3 is low in wolframite slime separation stage.In order to recover tungsten from this wolframite slime tailing,a research work had developed.The experiment determined the processing flowsheet of screening,roughing by centrifugal separator and HVC concentrator recovering.By this processing flow,a wolframite concentrate with WO3 grade of 28.04%and recovery of 49.20%can be received,and the WO3 grade in wolframite slime tailings is 0.142%.
