1, What is the raw material of activated bleaching earth?

A green-yellow water-swelling clay material was discovered near Rock River,Wyoming in 1898 by a U.S. Geological scholar, Wilbur C. Knight. This material was given the name “bentonite” because it was originally found in the place named "FortBeton". The global bentonite ore zone is mainly distributed in the areas of the circum-Pacific belt, the circum-Indian Ocean belt, and the Mediterranean-BlackSeabelt. Among them, the circum-Pacific belt is the main producing area. Chinese bentonite mineral resources belong to the circum-Pacific ore zone.


According to incomplete statistics, Chinese bentonite mineral resources have been more than eight billion tons, accounting for 60% of global quantity. More than 400 bentonite mines have been found and distributed in 23 provinces and regions of China.
