Yangyuan Renheng Fine Clay Co., Ltd., a wholly-owned subsidiary of Zhejiang Chang'an Renheng Technology Co., Ltd., is an important production base of the company. Its main raw material is bentonite ore extracted from its own mines. After more than half a year of stripping the covering layer, Yangyuan Renheng discovered more and better high-quality bentonite deposits than the original exploration data contained, with a total expected amount of one million tons.

After preliminary testing, the newly discovered high-quality bentonite mineral deposit can develop various high-value bentonite fine chemicals, which will provide important support for the future development and performance improvement of Chang'an Renheng!
