The first step in the wet process is to fractionate the kaolin slurry into a coarse and fine fraction through continuous centrifuges or by settling in large hydroseparators or vats. The coarse fraction can be used as filler in paper, plastics, paint, and adhesives and for many of the same applications as the dry processed kaolin.
