摘　　要：采用高梯度磁选作粗选、重选和磁选相结合的精选工艺流程回收某黑钨矿石,对原矿WO3品位0.413%的给矿,获得的钨精矿产率0.472%、钨精矿WO3品位66.03%、回收率为75.46%的技术指标,黑钨矿得到了较好的回收。The technological flowsheet of high - gradient magnetic separation used as roughing and the combination of gravity concentration and magnetic separation used as cleaning was adopted to recover a certain wolframite ore. As a result, from the ore feed containing WO3 0.413% , a wolf- ramite concentrate of WO3 66.03% with a recovery of 75.46% and the yield of 0. 472% was obtained. And the wolframite was recovered fairly good.
