摘　　要：针对福建某钨多金属选厂白钨矿回收存在粗精矿产率大、WO3品位低,加温精选水玻璃用量大、能耗高及钨精矿指标差等难题,文章通过试验研究,优化粗选段工艺流程并采用新型高效的QB-3抑制剂和CYP-01捕收剂,实现了粗选段白钨矿的高效富集,大幅降低钨粗精矿产率和钨加温精选水玻璃用量,有利于节能降耗。采用新的白钨矿浮选工艺,全流程闭路试验获得了产率0.10%、WO_(3)品位65.381%、回收率75.15%的钨精矿,实现了低品位难选白钨矿的高效综合回收。Aiming at the problems of scheelite recovery in a tungsten polymetal processing plant in Fujian Province,such as high yield of coarse concentrates,low WO3 grade,large amount of water glass for heated cleaning,high energy consumption and poor tungsten concentrate index,this paper optimized the process flow of the roughing process folw and adopted a new and efficient QB-3 depressant and CYP-01 collector to achieve efficient enrichment of scheelite in the roughing section through experimental research.Greatly reduce the yield of tungsten coarse concentrates and the amount of tungsten heating and water glass,which is conducive to energy saving and consumption reduction.Tungsten concentrate with yield of 0.10%,WO_(3) grade of 65.381% and recovery rate of 75.15% was obtained by using the new scheelite flotation process in the whole process.The comprehensive recovery of low-grade refractory scheelite was realized.
