Pugu Kaolin Mineral Composition

kaolin | clay | Britannica

Kaolin as found in nature usually contains varying amounts of other minerals such as muscovite, quartz, feldspar, and anatase. In addition, crude kaolin is frequently stained yellow by iron hydroxide pigments. It is often necessary to bleach the clay chemically to remove the iron pigment and to wash it with water to remove the other minerals in order to prepare kaolin for commercial use.

Kaolinite

Kaolinite is a layered silie clay mineral which forms from the chemical weathering of feldspar or other aluminum silie minerals. It is usually white, with occasionally a red color impurity due to iron oxide, or blue or brown from other minerals. Kaolinite has a low shrink–swell capacity and a low ionexchange capacity, making it ideal for many industrial appliions. Uses. During ...

Clays Statistics and Information

Six types of clays are mined in the United States: ball clay, bentonite, common clay, fire clay, fuller's earth, and kaolin. Mineral composition, plasticity, color, absorption qualities, firing characteristics, and clarifiion properties are a few of the characteristics used to distinguish between the different clay types. Major domestic markets for these clays are as

Residual strength of kaolin and bentonite: the influence ...

This Paper investigates further the roles of minerals and pore fluid composition on the residual strength of clayey soils. It describes and analyses tests on kaolin, bentonite and their mixtures exposed to distilled water and sodium choride solutions with given concentrations. The results show that the shear strength of kaolin is not affected by the solutions used, whereas the residual ...
