1.our company own the only natural soduim bentonite mine;
2.have higher quality than man made sodium bentonite
Liu Fang Zi bentonite deposits are inorganic substance of natural clay mine formed 140 million years ago in late Jurassic and early Cretaceous period due to ash accumulation and thermal effect from crustal movement and volcano eruption, after billions of years high temperature and high pressure effect. The verified deposits add up to 22 million tons in total, all of which are natural minerals of sodium bentonite. Rarely has there been such a large amount deposit and so good quality bentonite in China or even the whole Asia.
