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.
