Kaolin in
Egypt is localities in 3 main areas, namely Sinai, Red Sea coast, and Aswan
Kalabsha with a low grade ranging from 26% to 35% Al2O3 , accessory minerals,
and varying degree of ferrugination and TiO2 are observed in different
localities. Kaolins are exploited for a wide range of industrial applications,such as the production of paper, ceramics, plastics and paints. So, it has to
be refined to meet commercial specifications out.
Clays are processed by mechanical methods, such as
crushing, grinding, and screening, however, because clays are used in such awide range of applications, it is often necessary to use other mechanical and
chemical processes, such as drying, calcining, bleaching, blunging, and
extruding to prepare the material for use.
