Kaolin: processing, properties and applications

1991. 9. 1.  There are two basic methods of processing kaolin, a dry method or a wet process (Guillet and Kriens, 1984). The dry method is called air flotation which separates the clay from contaminants. The wet method produces water washed clay where the clays are fractionated, beneficiated or otherwise modified from their orig- inal state.

METHOD FOR PROCESSING KAOLIN CLAY ENGELHARD

An object of the invention is to provide a method for wet processing kaolin clay whereby the primary dispersant is retained on the clay through subsequent flocculation, bleaching, filtering and rinsing, with the result that the primary dispersant functions in conjunction with any dispersant subsequently added to provide predispersed spray-dried or slurried products with exceptionally good stabilities.

Kaolinite an overview ScienceDirect Topics

Kaolinite-enriched rocks are generally called kaolin or china clay [177]. This clay encloses a white mineral called dioctahedral phyllosilicate that is formed by chemical changes to aluminum silicate minerals including feldspar [178]. For ceramic applications, kaolin is heat treated and altered into Al 2 O 3.2SiO 2.2H 2 O.
