Calcite is one of the most important rock-forming minerals in the earth's crust. It can be formed in various geological processes and is a widely distributed calcium carbonate product. All members of the calcite group crystallize in the trigonal system, have perfect rhombohedral cleavage, and exhibit strong double refraction in transparent rhombohedrons.

Resource distribution

Calcite is a rock-forming mineral that accounts for more than 40% of the total crust, and its type is not less than 200. The source is all over the world.

Calcite Processing Plant

Calcite is rich in resources globally, and the high-quality calcite resources with calcium carbonate content ≥97% are also large. Therefore, at present, only performs simple washing and hand selection at the beginning of classification.
The processing flow for products below 400 mesh is like: raw ore-crushing-grinding-classifying
The purpose of crushing and grading is to produce a product that meets the fineness requirements of the application field. There are two kinds of superfine pulverization processes for calcite worldwide: dry method and wet method.
Technically, the dry process is generally used to produce D97 ≥ 3 ~ 5um products, the wet process is generally used to produce D97 ≤ 3 ~ 5um (D90 ≤ 2um) products


The calcite powder as a filling material, is most often used in artificial stone, Artificial floor tile, natural rubber, synthetic rubber, painting,plastics, Composite calcium new plastic, cable, papermaking, toothpaste, cosmetic,glass, medicine, paint, oil Ink,electric insulation, food, weave, fodder, binder,sealant, pitch, building materials, fire-barrier ceiling, and daily chemical series products.
