摘　　要：某钨矿原矿品位低,含WO30.24%,黑钨矿和白钨矿的矿物含量比约为55∶42,两者交生关系复杂,属复杂难选低品位黑白钨矿石。为了回收该矿石中的钨资源,首先进行了系统的工艺矿物学研究,查清影响钨选矿的矿物学因素。然后在此基础上进行了全浮、先磁后浮、浮-磁-浮、浮-磁-分级摇床重选、浮硫-分级摇床重选五种工艺流程方案的简单可选性对比试验研究,并对各方案的优缺点进行了详细的对比分析。最后推荐采用浮硫-分级摇床重选工艺流程作为有效回收该矿石中钨资源的试验原则流程,并给出合理化建议。A tungsten ore has a low grade, the WO3 rate reaching only 0.24 %. The mineral content ratio of wolframite to scheelite is about 55∶42. In addition, the symbiotic relationship between the two is complex.To recover tungsten resources in the ore, we performed systematic process mineralogy investigations into the complex refractory low-grade wolframite. On the basis of identifying mineralogical factors affecting tungsten beneficiation, we carried out a comparative experimental study on the feasibility of five process schemes, including full floating, magnetic first and then floating, floating-magnetic-floating, floating-magnetic-classification shaking table gravity separation, floating sulfur-classification shaking table gravity separation. The advantages and disadvantages of each scheme were compared and analyzed in detail. It is recommended that the flotation-classification shaking table gravity separation process be used as the experimental principle process for effectively recovering tungsten resources in the ore.
