In 1989, kaolin production worldwide was 20,000,000 tons per annum of processed kaolin with an annual profit of more than US$ 1,000,000,000 (Bristow, 1989). In 1993, the total consumption of processed kaolin in the world market rose to more than 25,000,000 tons and with substantially higher profits ( Harvey and Murray, 1997 ).
