Kaolin resources are abundant in China. More than 600 kaolin occurrences have been found and their resources are estimated at over 1.2 billion tons. Moreover, according to the prediction of the coal department, the prospective resources of sedimentary kaolins in coal measures of northern China may attain 18 billion tons. Thus it follows that the total kaolin resources in China may probably exceed 19 billion tons, ranking in the forefront of the world. By the end of 1997, 210 kaolin occurrences (including 11 superlarge ones, 28 large ones, 62 medium-sized ones and 109 small ones) had been explored and their retained reserves obtained. China’s retained kaolin reserves of categories B+C+D as of 1997 totalled 1,434.51 million tons.

Among the retained kaolin reserves, categories B+C reserves account for 24% of the total. Exploration or detailed reconnaissance has been conducted in 77% of the kaolin occurrences. Some major mines in Jiangsu, Hunan and Guangdong provinces show relatively high levels of geological work, with categories B+C reserves accounting for up to 35% to 80% of the total; whereas in some provinces only reconnaissance has been carried out in major mines and only category D retained reserves have been obtained.

Among the kaolin occurrences with retained reserves, those that have been used amount to 81 (including 5 superlarge ones, 9 large ones, 22 medium-sized ones and 45 small ones), distributed in Guangdong, Fujian, Jiangxi, Jiangsu, Hunan, Hubei, Inner Mongolia, Zhejiang, Sichuan and Yunnan, and their retained kaolin reserves total 590 million tons, making up 41% of the total, and may satisfy the demands for kaolin production in China till 2010 and in a still later period; 119 occurrences (including 6 superlarge ones, 18 large ones, 36 medium-sized ones and 59 small ones) are selectively usable, distributed in Shaanxi, Guangxi, Guangdong, Fujian, Jiangsu, Jiangxi, Hunan and Hainan, contributing 810 million tons of retained kaolin reserves which accounting for 57% of the total; 10 occurrences (including 1 large one, 4 medium-sized ones and 5 small ones) are difficult to use in the near future, distributed in Jiangxi, Anhui, Guangdong and Zhejiang, having 30 million tons of retained kaolin reserves, accounting for 2% of the total.
