These properties include: Color: Kaolin is typically white, although its color can vary depending on the presence of impurities. The whiteness is a sought-after property for numerous applications, such as in the paper industry. Non-toxicity: It is non-toxic, which makes it safe for various applications, including in cosmetics and pharmaceuticals.Web

The annual national demand for kaolin has been estimated at over 360,000 tonnes while local production is only about 125,000 tonnes. This leaves a gap of about 235,000 tonnes. Production process. Kaolin is by two major processing techniques. These are the wet and dry methods.Web

The main commercially important kaolin resources are the primary deposits in Cornwall and the sedimentary deposits in South Carolina and Georgia in the U.S.A. Annual world production is about 18 Mt (1 t = 10 3 kg). In 1981 the U.K. production was 2.6 x 10 6 t of which about 77 % represented paper filler and paper coating grades. About 15% of the …Web

Geopolymers have been intensively explored over the past several decades and considered as green materials and may be synthesised from natural sources and wastes.
