At present, China has 700 multiple kaolin mine , mine sites on 200 proven reserves of 30 billion tons, mine is more dispersed . Which kaolin 1.67 billion tons , mainly distributed in northern China 's northeast, northwest of the Carboniferous -Permian coal measures in order seam partings , seam roof and floor or a separate form .
Our country is coal-producing country , basically large mines are associated with kaolin , which is very rich in kaolin reserves . Department of kaolin 1996 non-coal reserves of 1.432 billion tons of proven industry .
Compared with other non-metallic resources , kaolin does not belong to our advantage in resources , such as per capita count is more shortages. And the distribution of kaolin resources scattered , taste is not high , the majority of kaolin ( foreign rarely ) , need to go through calcination or modified , for the paper coated with natural limitations.And kaolin associated coal mine because they belong to , difficult to scale exploitation . In China, the non-coal -based kaolin and kaolin reserves are considerable, but the vast majority of tubular kaolin, viscosity, and can not be used for paper coating .
According to the current understanding of the information , and only in Guangdong , Guangxi, Hebei Shahe kaolin resources can be developed for use in paper coating , so resources are very valuable . Shahe, Hebei in the late 1990s in the domestic market and the Maoming kaolin paper coating had a fierce competition, but now due to insufficient resources , gradually shrinking .
