Calcium carbonate has many natural uses as well as commercial ones. A commercial use of calcium carbonate is its use in antacids, as filler in the paper industry, used in decorating and construction as well as its heated form, marble. Calcium Carbonate is found in many grocery store products such as backing powder, dry-mix dessert mixes, dough, plastic, and wine |

Plastics |
| |
The Mineralogical and physio-chemical properties of any Calcium Carbonate and Dolomite plays a vital role in its use with any specific polymer. |
 |
| |
In the production of plastic compounds, mineral fillers are one of the additives that when incorporated in their formulation defines the quality of the final product. |
| |
The effect that fillers produce over the properties of the plastic, is highly dependent on the particle size, the distribution of the particle size, and the strength of the union between the filler particle and the polymeric matrix. |

Paints |
| |
Natural calcium carbonate has also established itself as ideal filler for paints and powder coatings |
| |
|
| |
A high degree of whiteness weather resistance, inertness, low abrasiveness, a high hiding power and a pH stabilizing effect are among its decisive advantages. |
 |
| |
Binder concentration can be regulated via particle shape and packing density, while opacity depends on particle fineness and particle size distribution. Hydrophobic calcites also improve the corrosion-inhibition and rheological properties of coating systems. |
| |
|
| |
A focal point in application technology research is the development of a new generation of extremely fine nature calcites which do not reagglomerate. Their primary particle diameter lies close to the theoretical maximum, so that the optimized fillers can replace expensive white pigments. |
| |
|
| |
Coating systems with high packing densities are involved in another development thrust. Here, shorter curing times are achieved due to the capability effect. This is particularly important in water based paints. |

Rubber |
 |
| |
Fine ground calcium carbonate is used in wide range of Rubber application to improve mechanical, rheological and optical properties. Application of the products ranges from Elastomers, hoses, seals, general moulding to footwear. Some of Calcium Carbonates are coated with coupling agents for improved dispersion in rubber matrix. |
