A New Kaolin Deposit in Western Africa: Mineralogical

Large kaolin deposits developed by weathering on Precambrian granitic rocks have been discovered in the Caluquembe area, Huíla province, Angola. To determine accuracy of analysis and to evaluate the kaolinite grade, a full-profile Rietveld refinement by X-ray Powder Diffraction (XRPD) and Thermal Gravimetric Analysis (TGA) was used. Caluquembe kaolin is composed mainly of kaolinite (44–93 ...

Kaolinite - Wikipedia

Kaolinite is a clay mineral, with the chemical composition Al2Si2O5(OH)4. It is an important industrial mineral. It is a layered silicate mineral, with one tetrahedral sheet of silica linked through oxygen atoms to one octahedral sheet of alumina octahedra. Rocks that are rich in kaolinite are known as kaolin /ˈkeɪəlɪn/ or china clay. The name "kaolin" is derived from "Gaoling", a Chinese village near

Kaolin - Earth Resources

There are high-grade transported kaolinitic clays at Axedale, Campbellfield, Hallora and Heyfield, and in the Latrobe Valley. The known Latrobe Valley deposits are at the base of the Morwell and Yallourn open-cut coal mines. Extensive kaolin 'ball clay' from these mines has been worked for use in white ceramics.

Clay Eating New Georgia Encyclopedia

Clay Eating. 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 Imerys

Kaolin, or ‘china clay’ as it is commonly called, is a hydrated aluminum silicate crystalline mineral formed over many millions of years by the hydrothermal decomposition of granite rocks. Hydrous kaolin is characterized by its fine particle size, plate-like or lamellar particle shape and chemical inertness.
