Areas Of Occurrence Of Kaolin

The occurrence of kaolinite clay is of a very large quantity in soils formed from the chemical weathering of rocks in tropical rainforest areas which has a hot and moist climate.Naturally, kaolin is found in other minerals in various quantities such as muscovite, quartz, feldspar, and anatase.

Kaolin clay Britannica

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

Kaolinite: Structure, Morphology and Use Soil Minerals

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

Land Reclamation . After the kaolin is removed, the land is carefully reclaimed and restored by contouring and grading the surfaces to blend with the surrounding terrain.Reclaimed lands are suitable for a wide variety of uses including agriculture, forest production and wildlife. Since 1969, 80 percent of all lands mined have been reclaimed or are in the process of being reclaimed.
