Bentonite is a non-metallic mineral with montmorillonite as the main mineral component. The montmorillonite structure is a 2: 1 type crystal structure composed of two silicon-oxygen tetrahedrons sandwiched with a layer of aluminum octahedron. Anshan talc powder is due to montmorillonite There are certain cations in the layered structure formed by the unit cell, such as Cu, Mg, Na, K, etc., the interaction of these cations with the montmorillonite unit cell is very unstable easily exchanged by other cations, so it has better ion exchange Sex. It has been applied in more than 100 departments in 24 fields of industrial agricultural production abroad.

Bentonite ore is a multi-purpose mineral, its quality application fields mainly depend on the content type of montmorillonite its chemical properties. Therefore, its development utilization must be different for different mines for different functions. Such as the production of activated clay, calcium-based to sodium-based drilling drilling grouting for oil drilling, instead of starch for spinning, printing dyeing slurry, internal external wall coatings on building materials, preparation of organic bentonite, synthesis of 4A zeolite with bentonite, production Silica, etc.
