Recent advances in lithium extraction from lithium-bearing clay

Many Li-bearing clay mineral resources have been discovered in specific regions in China and Europe. Thus, Li extraction from Li-bearing clay minerals could ensure the Li supply and expand the Li market (Malhi, 2018). The intense exploration and processing of Li-bearing clay minerals will provide a new direction for global Li resourceClay dust coming from the clay mining processing unit.

Recent advances in lithium extraction from lithium-bearing clay

Lithium-bearing clay minerals are important alternative mineral sources, which can enrich the Li market and ensure the supply of Li products. Lithium-bearing clay minerals, in general consist of a 2:1 layer structure, has a good ion exchange performance. Therefore, the extraction of Li from Li-bearing clay minerals through acidification, saltOn the other hand, china clay is a widely used white filler in the rubber industry. Depending on particle size, it can be used as a semi-reinforcing filler (hard clay) or a non-reinforcing filler (soft clay). Common elastomer applications include chemical liners, bicycle tires, conveyor belts, shoe soles, gaskets, and flooring. Keywords. China clayChina Clay or Kaolin SpringerLink

China Clay. (Kaolin) Processing. Kaolin (china clay) is a hydrated aluminum silicate crystalline mineral (kaolinite) 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.Kaolin (or china clay), ball clay and bentonite are the dominant ‘industrial clays’, and are mined for a wide variety of uses ( Table 3.1 ), which exploit the special properties of each of the three clay types: Kaolin (china clay) — is chemically inert and can be prepared as a white powder specified (in part) according to its whitenessIndustrial clays: kaolin (china clay), ball clay and bentonite
