In addition to the technical aspects of mining and processing, the social, environmental, and economic impacts of kaolin production are managed at each stage of the mining life cycle. Discussed herein are aspects of the history of kaolin mining, the classification of kaolin mines, the processing of kaolin, and the life cycle of mining.
Read MoreLand Reclamation . After the kaolin is removed, the land is carefully reclaimed and restored by contouring and grading the surfaces to blend with the surrounding terrain.Reclaimed lands are suitable for a wide variety of uses including agriculture, forest production and wildlife. Since 1969, 80 percent of all lands mined have been reclaimed or are in the process of being reclaimed.

Read MoreGeopolymers based on kaolinitic sludge waste developed compressive strengths of up to 70 MPa after one day of curing. This elucidates that geopolymerization can be a feasible technological solution for the valorization and exploitation of kaolinitic sludge waste from the mining industry for the production of cementitious matrices.
