Clay mineral Chemical and physical properties
Clay mineral Clay mineral Chemical and physical properties: Depending on deficiency in the positive or negative charge balance (locally or overall) of mineral structures, clay minerals are able to adsorb certain ions and anions and retain them around the outside of the structural unit in an exchangeable state, generally without affecting the basic silie structure.
Evaluation of Nigerian Source of Kaolin as A Raw Material
The study revealed that the mined kaolin can be utilized for the synthesis of mullite after physical beneficiation. Advantages of using this presently available Nigerian source of kaolin powder as the starting material for mullite synthesis are (1) low temperature mullitization and (2) unique microstructure.
Bentonite Wikipedia
Bentonite (/ ˈ b ɛ n t ə n ʌ ɪ t /) is an absorbent aluminium phyllosilie clay consisting mostly of montmorillonite.It was named by Wilbur C. Knight in 1898 after the Cretaceous Benton Shale near Rock River, Wyoming.. The different types of bentonite are each named after the respective dominant element, such as potassium (K), sodium (Na), calcium (Ca), and aluminium (Al).
US7122080B2 Integrated process for simultaneous
The present invention provides an improved method of beneficiating and dewatering kaolin clays. The product of the improved process is a brightened, dewatered kaolin, suitable for use in pigments and paper coating compositions. The improved beneficiation process provides refined kaolin for pigments and other purposes of the same or better quality as prior art processes, but with the use of

Kaolinite Wikipedia
Kaolinite (/ ˈ k eɪ ə l ɪ n aɪ t /) is a clay mineral, part of the group of industrial minerals with the chemical composition Al 2 Si 2 O 5 4.It is a layered silie mineral, with one tetrahedral sheet of silica (SiO 4) linked through oxygen atoms to one octahedral sheet of alumina (AlO 6) octahedra. Rocks that are rich in kaolinite are known as kaolin / ˈ k eɪ ə l ɪ n / or china clay.
