从低品位多金属矿中回收细粒级黑白钨矿的研究

摘要

采用新型选矿药剂TAB -3、浮-磁-浮工艺流程,从多金属矿中回收细粒级黑白钨.工业试验获得白钨精矿WO3品位68.06％、回收率50.03％,黑钨精矿WO3品位35.85％、回收率25.80％,总钨回收率75.83％,取得了黑白钨共生矿的较好选矿指标.%Adopting a flowsheet of flotation-magnetic separation-flotation, and using a new flotation reagent, TAB -3,fine tungsten can be effectively reclaimed from multi-metallic ores. Eventually, a scheelite concentrate with a grade of68.06% WO3 and a recovery of 50.03% , and a wolframite concentrate with a grade of 35.85% W03 and a recovery of25. 80% , can be obtained from the site test, and the total tungsten recovery amounts to be 75. 83% , indicating thatgood index can be achieved for this intergrown ore of wolframite and scheelite.
