The ingestion of kaolin, also known as "white dirt," "chalk," or "white clay," is a type of pica (eating of nonfood substances). Found in the central Piedmont section of Georgia, vast deposits of kaolin are mined around Sandersville, in the area between Macon and Augusta.Kaolin is a naturally deposited clay used in the manufacture of ceramics as well as in coatings for paper and textiles.

Clay mineral - Clay mineral - Occurrence: All types of clay minerals have been reported in soils. Allophane, imogolite, hydrated halloysite, and halloysite are dominant components in ando soils, which are the soils developed on volcanic ash. Smectite is usually the sole dominant component in vertisols, which are clayey soils. Smectite and illite, with occasional small amounts of .

The volume of typical kaolinite particle is about 3 x 10 – 11 mm 3, considering the particle as a hexagonal prism of equal sides of about 0.5 µm (0.0005 mm) size and about 0.05µm (0.00005 mm) thickness.Taking the density of soil solids as 2.7 g/cc, the weight of a typical kaolinite particle is about 8 ×10 – 14 g.. The surface area per unit weight, known as specific surface, is about 15 ...
Kaolin has a range of industrial applications grouped into three main market areas: – Paper, ceramics and specialty minerals. Paper accounts for the majority of sales at around 70% of total sales. It is used in two distinct ways, as a filler between the paper fibres, to improve quality and as a coating, to enhance the surface ...
to quartz–kaolin rock adjacent to areas of intense greisenisation (Brown & Stroud 1997). The area east of Bourke appears to have considerable potential for transported and residual kaolin deposits associated with deeply weathered Silurian granites, but has been subject to only limited exploration to date.
Kaolin is a mixture consisting principally of the mineral kaolinite and containing varying amounts of other minerals such as muscovite, quartz, feldspar, and anatase. Also known as china clay, kaolin is a soft white clay that is an essential ingredient in the manufacture of china and porcelain and is widely used in the making of paper, rubber ...

Kaolin occurrence. The occurrence of Kaolinite clay is of a very large quantity in soils formed from the chemical weathering of rocks in tropical rainforest areas whi ch has a hot and moist climate. Naturally, kaolin is found in other minerals in various quantities such as muscovite, quartz, feldspar, and anatase.
Kaolin, also called china clay, soft white clay that is an essential ingredient in the manufacture of china and porcelain and is widely used in the making of paper, rubber, paint, and many other products. Kaolin is named after the hill in China (Kao-ling) from which it was mined for centuries. Samples of kaolin were first sent to Europe by a French Jesuit missionary around 1700 as examples of ...
