occurring kaolin clay at a temperature greater than 450 °C and a heating time of approximately 30 minutes. The process typically converts 20-80% of the clay into calcined kaolin The heating process drives off water from the mineral kaolinite (Al2Si2O5(OH)4) the main constituent of kaolin clay and collapses the material structure resulting in an

Calcined Clay - Ashok Mineral Enterprises

Calcined Kaolin is used as a functional extender in paint. Calcined kaolin has proven to be an excellent extender for titanium dioxide (white) pigment in paint. This is because Kaolin is chemically inert has high covering power gives desirable flow properties and reduces the amount of expensive pigments required.

Calcined Kaolin - Digitalfire

Calcined kaolin (also called metakaolin) is a powdered white non-plastic material. It is kaolin that has been fired (in a rotary calcining kiln) high enough to remove the 12% (approx) crystal water.

11.25 Clay Processing

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 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

Extraction of Aluminium from Kaolin: a Comparative Study of .

3.1. Hydrometallurgical Treatment of Calcined Kaolin In Fig. 2 the extraction of Al and Si from the calcined kaolin is given as a function of leaching time and the acid-solution used. According to Fig. 2(a) the leaching of Al from the calcined kaolin with HCl HNO 3 H 2 SO 4 and C 2 H 2 O 4 is a fast process and totally completed after 6 h.
