摘　　要：膨润土作为新兴的非金属矿物,广泛应用于食品、化工、医药等多个领域,高纯膨润土更是具有高附加值。针对膨润土提纯工艺及方法进行了概括,指出了不同方法的工艺设备、提纯原理、分离效果及现存问题。对其各工艺方法研究的主要进展进行了讨论,归纳了膨润土提纯常用工艺的类型、影响因素以及应用的广泛性。并在此基础上,对高纯膨润土制备的研究前景进行了展望。As new emerging minerals, bentonite has been widely used in food, chemical, pharma- ceutical and other fields, and high purity bentonite has more added values. Summarize the bentonite puri- fication process and methods, point out the process and equipment, purification principles, purification effectiveness and existing problems of different methods, discuss the main progress of research on benton- ite purification method, and summaries the commonly used technology, influence factors and universality of application. On the basis of this, the prospect on preparation study of high purity bentonite was con- ducted.
