A process flow diagram for kaolin mining and dry processing is presented in Figure 11.25-1, and Figure 11.25-2 illustrates the wet processing of kaolin. In the dry process, the raw material is crushed to the desired size, dried in rotary dryers, pulverized and air-floated to remove most of the coarse grit. Wet processing of kaolin begins with
EICL has kaolin mines and two wet processing units in Kerala. The calcined clay products are produced only from Thonakkal; whereas the rest is from both Veli & Thonakkal. The total installed capacity of EICL is 300,000 Tonnes of processed kaolin/annum. EICL has a wide range of products in the portfolio to cater to the various market needs.
The number of domestic suppliers of coating grade kaolin products has declined from 7 in 1985 to 5 today. Kaolin Processing. Kaolin deposits are non-uniform in quality and contain various discolorants and impurities. As a result, producers employ a variety of different technologies to process the ore for paper grade products.
Calcined Kaolin or Calcined Clay is also called as Metakaolin or Chamotte. It is an an anhydrous aluminium silicate, a white powdered non-plastic material). It is produced when raw kaolin or more popularly known as Clay or China Clay is fired enough to reduce its crystalline water content via a process known as Calcination.
The main commercially important kaolin resources at the present time are the primary deposits of Cornwall in England and the sedimentary deposits in Georgia and South Carolina in the USA.
