摘　　要：为验证湖南某白钨矿分级-重选联合预抛废在工业上的可行性,进行了工业分流试验和浮选对比小型试验。结果表明,在适宜条件下,采用筛分-螺旋溜槽预抛工艺,可抛掉产率25.50%、钨品位0.034%、钨损失率2.99%的抛废产品;抛废后再进行浮选,精矿产品品位和回收率均高于分级溢流直接浮选所得精矿产品。To examine the industrial feasibility of pre⁃discarding by using screening classification combined with gravity separation in processing of a scheelite ore from Hunan Province,industrial distributary and flotation trial tests were carried out.The results show that a process consisting of screening and spiral chute discarding under optimized conditions can discard tailings grading 0.034%WO3 with a yield of 25.50%in mass,leading to tungsten loss of only 2.99%.With this pre⁃discarding before flotation process,both the grade and recovery of the final flotation concentrate are improved,compared to the concentrate obtained from direct flotation of overflow product.
