Which also called ground calcium carbonate, is produced by natural superior calcite, which has high purity and whiteness. The size ranges from under 400 mesh which is called primary products, to 3000 mesh or above, depending on your requirement.
Heavy (Ground) Calcium Carbonate is widely used as filler in plastic, paint, paper-making, rubber, pharmacy, feed, daily chemical, ceramics, adhesives and ink industry.

Calcium carbonate decomposes to form carbon dioxide and lime, an important material in making steel, glass, and paper. Because of its antacid properties, calcium carbonate is used in industrial settings to neutralize acidic conditions in both soil and water.
acid process papermaking in the coated, ground wood and paperboard markets, PCC is well established as a filler and coating pigment for premium quality paper products. ... Constantly improving quality targets make the brightness of paper, and thus PCC, an increasingly important factor, using in our toothpaste.
Description
Calcite Powder
Calcite Powder or Limestone is a common sedimentary rock composed primarily of the calcium carbonate mineral, calcite (CaCO3). Calcite Powder constitutes approximately 10 percent of the sedimentary rocks exposed on the earth's surface. Calcite Powder is formed either by direct crystallization from water (usually seawater) or by the accumulation of sea animal shells and shell fragments.
Features:
Higher mechanical properties in thermoplastic applications
Higher flow properties
Prevents chalking
Gloss and whiteness in paints and powder coating applications
Excellent dispersion properties
Calcite is a calcium carbonate mineral (minerals containing CO3) that is usually white. It is one of the most important minerals in the world and is extremely common. It can be found in the three main types of rocks (sedimentary, metamorphic and igneous rocks) and, in the form of marble or limestone, makes up much of the Earths crust. Calcite is one of the main minerals in limestone, marble and shells of marine species. Interestingly, calcite has more practical uses than most other minerals in the world. It has the same chemical formula as other types of calcium carbonate, such as limestone, marble and chalk: CaCO3. It comes in bright white color and it has nodular particle size with strong crystal structure.
The common features are as follows:
Rapid and complete dispersion
Very Low abrassion at high loading
Very low moisture content
Good compatibility with polymers and other additives
Better impact strength of polymer compound as compared to uncoated material
Applications:
As a formation bridging and filter-cake sealing agent in drilling fluids.
As a weighting material to increase the density of drilling fluids, to control downhole pressures.
As an extender in paints, especially in matte emulsion paints.
As a filler in plastics (example - 15 to 20% loading of chalk in PVC drain pipe) as well as thermosetting resins.
In a wide range of trade and DIY adhesives, sealants, and decorating fillers.
In setting stained glass windows, along with putty.
As a resist to prevent glass from sticking to kiln shelves when firing glazes and paints at high temperature.
As a common ingredient for many glazes, in ceramics/glazing applications.
In the production of glossy paper, replacing kaolin.
For the purpose of purifying iron steel materials, in a blast furnace, from iron ore.
As a building material in its own right (like marble) or limestone aggregate for the purpose of road-building and construction.
For making mortar, which is used in bonding bricks, concrete blocks, stones and tiles.
As a filler material for latex gloves, as precipitated Calcium carbonate (pre-dispersed in slurry form).
As a major component of blackboard chalk.
As an inert filler for tablets and other pharmaceuticals.
As a pH corrector in swimming pools, for maintaining alkalinity buffer to offset the acidic properties of the disinfectant agent.
In the production of toothpaste.
