Methods of Beneficiation of Kankara Kaolin. Ajayi, O. A S. S. Adefila. More Details. Beneficiation Process of Kaolinite Clay: Kaolin Processing. Kaolin is an important industrial mineral having numerous uses and requiring various market specifiions. High brightness kaolin clays represent a continuing challenge to the producer.

1. Introduction - file.scirp.org

Kaolin is a fine clay mineral cream to dark brown, colored by iron oxides/hydroxides (and/or rutile/anatase). Its major constituent is kaolinite (Al 2 O 3 ∙2SiO 2 ∙2H 2 O), a hydrous aluminum silicate with a single silica tetra hedral layer linked through oxygen atoms to a single alumina octa hedral layer.

Raw kaolin and diatomaceous earth had a SiO 2 /Al 2 O 3 molar ratio of 2.2 and 15, respectively. This ratio was successfully increased by acid leaching to 33 and 44 for kaolin and diatomaceous earth, respectively. Acid leaching also reduced significantly the concentration of impurities in both materials.
