As a very important non-metallic mineral, kaolin plays a very critical role in industrial using and is widely used in various industries such as ceramic, construction, paper making, filler material, painting, cosmetics as well as other applications. The concentration for kaolin
Water washing concentration is commonly used to separate kaolin from impurities. First the raw ore is made to slurry and dispersing agent is added to make the slurry density 5%-14%, then impurity minerals with bigger size such as quartz, feldspar, mica as well as other big size impurities will be settling faster than kaolin. Thus, kaolin can be concentrated.
