Mining Method Of Kaolin
Kaolin
Kaolin mining activities are restricted to near-surface (less than 150 meters) ore bodies that are 3 to 15 meters thick. Once the ore has been extracted, mine reclamation activities are conducted to restore the landscape to a pristine state. Kaolin is most commonly used in the paper-coating industry. It is also used as a filler (added to ...
