摘　　要：江西某钨矿选矿厂细泥段WO_(3)回收率较低,严重影响企业的经济效益。为进一步提高该钨矿细泥段WO_(3)回收率,利用悬浮震动带式精选机对摇床尾矿进行了选矿试验研究。结果表明,悬浮震动带式精选机对细粒钨矿具有富集比大、回收率高的优势,在给矿浓度为15%、处理量为112.4 kg/h、震动速度370 r/min、皮带速度为150 cm/min时,分选效果最优。获得了WO_(3)品位为20.62%、回收率达64.29%的钨精矿,该试验结果为后续生产作业提供了可靠依据。For an improvement of the recovery rate of WO_(3) in the fine slime section of a tungsten ore,the experimental research on beneficiation of the shaking table tailings was carried out by using the suspension vibrating belt concentrator.The results show that the new technology has the advantages of large enrichment ratio and high recovery rate for fine tungsten ore.With the following optimal conditions,including:feed concentration of 15%,processing capacity of 112.4 kg/h,vibration speed 370 r/min,and belt speed of 150 cm/min,a recovery rate of 64.29%was obtained with tungsten concentrate WO_(3) grade of 20.62%.The testing results provide a reliable basis for subsequent production operations.
