Gray-black kaolinitic claystones of industrial value are abundant in Upper Carboniferous–Lower Permian coal-bearing strata of the Datong Coalfield of northern China. The main types are tonsteins and cryptocrystalline kaolinitic claystones, distinguished by the thinness and greater crystallinity of kaolinite in the former and by the presence of detrital illite and …
Kaolinite is a clay mineral with a chemical composition of Si 2 Al 2 O 5 (OH) 4, the chemical composition is Al 2 O 3 (39.50%), SiO 2 (46.54%) and H 2 O (13.96%). The crystal is a layered silicate mineral of the triclinic system [31].Generally, kaolinite is white color, sometimes the impurities contain red, blue or brown, and in the form of pseudo-hexagonal plates.

The sharp increase in the demand for lithium (Li) for high-energy-storage battery materials due to its high specific energy and low negative chemical potential render Li a geopolitically significant resource. It is urgent to develop a low-cost, efficient method to improve lithium extraction. Herein, Li ion (Li+) adsorption in coal-bearing strata kaolinite (CSK) was …
for this conclusion. Therefore, to efficiently utilize kaolinite resources, it is necessary to study their crystallinity. The crystallinity of kaolinite is mainly related to the stacking order–disorder. Kaolinite (Al 4[Si 4O 10](OH) 8) (Pauling 1930) is a typical 1:1 dioctahedral layered silicate
Therefore, the research on the separation of clay lithium resource is an important topic in the future. The main minerals in clay-lithium resource include chlorite, kaolinite, diaspora, montmorillonite and illite. Some flotation researches were carried out on it, which could provide useful references for the separation of clay-type lithium ...

X-type zeolite was synthesized from kaolin previously dealuminated through reaction with sulfuric acid at high temperature to raise its SiO2/Al2O3 ratio. All of the steps in the synthesis of X-type zeolite from dealuminated kaolin were studied. Parameters analyzed included temperature, time, stirring speed, and composition ratios. The optimum values for the …
