Fuquan Mountain diatomite mine and Puqiao diatomite mine are the two largest diatomite mines of Zhejiang Province. And Shengzhou diatomite is the advantage of non-metallic mineral, the diatomite reserves ranked first in China. Diatomite mining at present, more than 150,000 tons a year, selling the country's 23 provinces and cities and worldwide, which have become the main origin of diatomite. The Mine area is about 100 square meters, and the thickness of deposit is about 48-52 m. The proved reserves are 45 million tons and more than 200 million tons of reserves in the future. Shengzhou diatomite mine area is suitable for open mining with the huge development potential.
