摘　　要：以苯甲羟肟酸与辅助捕收剂WT为组合浮选药剂,采用浮选、YTF-C微细摇床精选和脱硫的工艺回收微细粒钨矿.工业试验结果表明,当浮选给矿品位(WO3)0.199%,-30μm粒级(WO3)的质量分数达90%以上时,获得品位(WO3)47.30%、回收率52.34%的钨精矿.该技术对回收微细粒钨矿有一定的借鉴作用.This paper introduces a new flowsheet to recovery fine wolframite. It includes three stages： First, the fine wolframite was flotated using benzyl hydroxmic acid and WT as collectors. In this stage, when the flotation feed grade was 0.199% WO3 with wt. 90% content of fine particle （size. -30μm）, the WO3 grade of the industrial test flotation rough concentrate reached 3. 930/40 with a recovery of 78.75%. Secondly, the flotation rough concentrate was further treated by using an YTF-C type shaking table. Finally, the shaking table concentrate was treated by using sulphide flotation. The WO3 grade of final concentrate of 47.30% with a recovery of 52. 34% （vs. the flotation feed） was obtained. This new flowsheet essentially solved the difficult recovery problem of fine wolframite.
