采用螺旋溜槽粗选丢尾，ＳＱＣ湿式强磁选－摇床富集获粗精矿；粗精矿浮选脱硫后再以摇床精选获得最终白钨精矿，即重－磁－浮－重的流程是综合回收永平铜矿铜硫浮选尾矿中白钨的较合理工艺。该工艺扩大试验指标为：白钨精矿含ＷＯ３６６．８３％，回收率１７．４４％，产品质量符合ＧＢ－２８２５－８１一级Ⅰ类标准。工艺技术可行，操作控制简便，分选指标稳定，扩大试验所获技术参数和指标可作为该矿尾矿综合回收白钨系统的建设设计依据
Using spiral chute crude roughening, SQC wet magnetic separation - shaker enriched by crude concentrate; crude concentrate flotation desulfurization and then shaker selection final scheelite, that is, heavy - magnetic - floating - Heavy process is a comprehensive recovery of Yongping copper and sulfur flotation tailing of scheelite more reasonable process. The process to expand the test indicators: scheelite containing WO366.83%, the recovery rate of 17.44%, product quality in line with GB-2825-81 a Class I standard. Process technology is feasible, operation control is simple, the sorting index is stable, and the technical parameters and indexes obtained by expanding the test can be used as the design basis for the comprehensive recovery of scheelite system
