The mining and processing of China Clay (Kaolin) begins with exploration. When China Clay (Kaolin) deposits are encountered, core samples of the deposits are extracted and sent to a laboratory for testing. Thousands of acres are drilled and thousands of feet of sample are tested to yield a handful of acceptable mining sites.
