Traditional and new applications for kaolin, smectite
Air classification is used in the dry processing of kaolin, bentonite, and palygorskite–sepiolite to remove quartz, mica, and other non-clay minerals and to produce various size fractions. This process has been significantly improved so that size classifications of −44, 20, 10 and 5 μm can be produced.Web
