Diatomite is formed by diatom-the remains of the unicellular water plant. The composition is a kind of opal, chemically we also call it SiO2.nH2O, the amorphous SiO2. Diatomite has some unique properties, such as: regular structural characterization non-micropore, larger specific surface area and larger pore volume, lower density, stronger adsorbent, better suspension chemical stability, worse conductivity by sound, heat and current, neutral point of the PH value, nontoxic and odourless, thus diatomite series products are widely used in the life.

Jilin Yuantong Mineral Co., Ltd. is wholly-owned subsidiary company of Beijing Dadi Yuantong(Group) Co., Ltd. The company holds diatomite minerals and professionally mines, manufactures, sales and researches diatomite series products.
Beginning, Yuantong Dadi Co., Ltd. expanded rapidly by different ways, such as investment, joint venture, acquisition etc. Now, the company has acquired 6 diatomite companies, it also sets up 2 wholly-owned companies and a China-Japan joint venture company. So now, Jilin Yuantong Co., Ltd. has become the biggest company of China in diatomite industry.
