蒙脱石提纯研究进展

总结了蒙脱石的各种提纯方法及其试验原理和提纯分离效果。主要涉及重力选矿、水力分析、絮凝法、离心分离和化学提纯。对电泳法提纯作了简介。研究证实，与蒙脱石粒度相近的方石英和石英微粒等杂质很难去除。氢氧化钠溶蚀法会对蒙脱石、石英和方石英同时产生溶蚀，引入新的物相杂质。

The Progress of Research on Montmorillonite Purification

In this paper,the crystal structure of montmorillonite is introduced and the purification methods((including) gravity separation,hydraulic classification,flocculation,centrifugal separation and chemical purification),the purification principles and purification effectiveness of the methods were summarized.The eletrophoresis,as a physical purification method,was also briefly introduced.It is found that it is very difficult to separate the cristobalite and quartz with similar size with montmorillonte from montmorillonte.Montmorillonite,quartz and cristobalite can be corroded by sodium hydroxide solution,but will introduce new impurity phase similar to zeolite.
