摘　　要：高岭土是一种重要的非金属矿产资源,具有良好的吸附性、可塑性和稳定性等,被广泛应用于造纸、陶瓷、橡胶和耐火材料等材料制备领域。但我国生产的高岭土产品质量较低,优质高岭土依赖进口,优化及创新高岭土提纯工艺至关重要。系统的介绍了高岭土的重选、磁选、浮选、浸出、化学漂白和焙烧等提纯工艺,以及高岭土、改性高岭土和纳米高岭土的应用研究进展。Kaolin is an important non-metallic mineral resource with good application properties such as adsorption,plasticity and stability.It is widely used for material preparation fields such as papermaking,ceramics,rubber,refractory material and so on.However the quality of kaolin produced in China is relatively low.High-quality kaolin usually relies on imports.It is crucial to optimize and innovate the kaolin purification process.The purification processes of kaolin,such as gravity separation,magnetic separation,flotation,leaching,chemical bleaching,roasting,and the application progress of kaolin,modified kaolin and nano-kaolin have been systematically introduced in this paper.
