某低品位黑白钨矿选矿试验研究

摘要

For studying the low-grade wolframite and scheelite ore of WO3 grade of 0.23% , according to the principle process of mixed floating wolframite and scheelite -Peter Lavrov law separation of scheelite -Shaking table fractionated recovery of wolframite,suitable grinding fineness and the appropriate amount of reagent were studied. The final available WO3 grade of scheelite concentrate, wolframite concentratel, wolframite concentrate 2 is 65.43% ,50. 11% ,31.65% respectively, and recovery each is 51.21% ,26.14% ,13.76% .total recovery of tungsten is 91.11%.%以WO3品位为0.23％的某低品位黑白钨矿为研究对象,按混浮黑白钨矿—彼得罗夫法分离白钨矿—摇床分粒级回收黑钨矿的原则流程进行了适宜的磨矿细度、合适药剂用量研究,最终获得的白钨精矿、黑钨精矿1和黑钨精矿2的WO3品位分别为65.43％、50.11％、31.65％,回收率分别为51.21％、26.14％、13.76％,钨总回收率为91.11％.
