Kaolinite Wikipedia

Kaolinite (/ ˈ k eɪ ə l ɪ n aɪ t /) is a clay mineral, with the chemical composition Al 2 Si 2 O 5 4.It is an important industrial mineral.It is a layered silicate 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.

Kaolin

Kaolin is a clay composed primarily of the hydrated aluminosilicate mineral kaolinite (Al 2 O 3. 2SiO 2. 2H 2 O) with minor amounts of quartz, feldspar, mica, chlorite and other clay minerals. It is distinguished from other clays by its softness, whiteness and ease of dispersion in water. Primary kaolin deposits were formed by the alteration of

Overview. The geological unit called Charentes basin is composed of Eocene and Oligocene deposits, laid above karstic limestone formations of the Campanian, in the north of the Aquitaine Basin.The Charentes basin is named after the departments of Charente and Charente-Maritime.The kaolin clays of Charentes belong to this mainly continental formation often referred as siderolithic, of which the

Occurrence Modes of Niobium in Kaolin Clay From Guizhou, China

Niobium in kaolin clay from the Late Permian sequences was reported in the range of several hundreds of micrograms per gram and was considered as a potential resource for its high concentrations and large areal distribution. Ti-bearing minerals associated with kaolin clay were identified as the main host phase for niobium in some case studies.
