摘　　要：针对某硫化矿尾矿含WO_3 0.32%,具有较大的回收价值,但采用常规的重选法难以回收的现实困难,研究以该尾矿为研究对象,在工艺矿物学研究的基础上,采用"预先脱硫—高梯度强磁选—黑钨矿浮选"的工艺流程综合回收该尾矿中的黑钨资源。结果表明,该工艺全流程闭路试验可获得含WO_3 50.93%,回收率68.44%的黑钨精矿,浮选作业回收率达81.93%,较好地实现了黑钨矿的有效回收。The WO3 content in a sulfide ore tailing reaches as high as 0.32 %. However, it is difficult to recover by conventional gravity concentration. On the basis of the process mineralogy, the process of ＂pre desulfurization - high gradient magnetic separation-wolframite flotation＂ was put forward. The results indicated that the whole process closed circuit test can obtain the wolframite concentrate with WO3 grade of 50.93 % and recovery of 68.44 %. The flotation recovery rate is 81.93 %, achieving the effective of wolframite.
