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.
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 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.
