【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.更多还原

【Abstract】 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:-30 μm),the WO3 grade of the industrial test flotation rough concentrate reached 3.93% 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.更多还原
