The process of kaolin refining is not complicated but each step of the process needs to be optimized. The raw material is excavated and taken by truck to large blungers in which the material is dispersed in water. A dispersant agent prevents the material from settling in the system.
Metakaolin is a layered aluminosilicate material which is used in cements as a pozzolanic additive and is produced by dehydroxylation of kaolinite clay at temperatures of 500––800 °C [107,108].It is frequently used as an SCM in blends with PC [61,109]. 29 Si and 27 Al MAS NMR studies of metakaolin have shown that it consists of alternating buckled …
The final product of kaolin production is a high-quality clay powder that is used in a wide range of applications. In the paper industry, kaolin is used as a filler to improve the brightness, opacity, and smoothness of paper products. In the ceramics industry, kaolin is used as a raw material for making porcelain, pottery, and tiles.
Kaolin Mining and Processing Extraction Methods. Kaolin is typically mined through open-pit mining methods. The extraction process begins by clearing away overburden before excavating strata-rich with kaolin deposits for extraction. Once mined, raw kaolin goes through processing to eliminate impurities and improve quality. …
