Mineral deposit of montmorillonite in Chifeng region, Inner Mongolia belongs to hydrothermal alteration type deposit, to form magmatic rocks, sedimentary, etc. (magnesium-rich silicate, iron magnesium silicate minerals) in weathering crust, in the latter part of the volcanic eruption, in the late cycle low alkaline environment, formed by the action of weathering and hydrothermal alteration of the gas-liquid and surface water , showing layered, lenticular output.

Original montmorillonite ore presents a variety of colors white, gray white, pink white, brick red, light green, purple, etc because of content change of iron ions, calcium ions, manganese ions, sodium ions, etc. in the lattice structure, presented waxy luster and soap-like fracture, has a good adsorption, suspension, colloidal dispersion, bonding and ion-exchange and so on.

Due to gradual change between the seam and distribution changes of metal ions (mainly Na +, Ca2 +, Fe3 +, Mn2 +) in double octahedral layers, the appearance of the color will be  a corresponding change.Hezhengmei Company is always strict with choosing original ore, after strictly inspecting montmorillonite content and ion exchange capacity etc indicator, it can be going on the next step.

In summary, different batch products produced by our company, color maybe have some changes because of seam change, this is decided by original ore, there are no direct relationship between montmorillonite color and content, grade, we guarantee, all products manufactured by our company will meet the targets set forth in the corporate standards, please rest assured customers use!
