摘　　要：采用浸泡、脱盐、旋流器一粗两精分选等提纯工艺,从原矿品位75%左右的新疆某地膨润土获得蒙脱石含量为97.59%的精矿,研究了不同浓度、压力等条件对提纯效果的影响,并通过SEM照片分析了剩余杂质难以去除的原因。Taking a bentonite with the ore grade of 75% from Xinjiang as the object of the experimental study,the effects of concentration and pressure on thg purification efficiency have been investigated. A concentrate with the grade of 97.59% was gained by centrifugation and hydrocyclone treatments. The causes of impurities that is difficult- to removed were identified by SEM.
