Calcium carbonate (CaCO3), usually found in the form of calcite and aragonite, is the most common complex on Earth.

Calcium carbonate (CaCO3), usually found in the form of calcite and aragonite, is the most common complex on Earth.

Calcium carbonate is not only the main component of marble, limestone and dolomite but is also found in bones, teeth, crustacean shells, corals, muscles, snails and protozoa. Another form of calcium carbonate is the mineral nepheline, which can precipitate into microcrystals.

Calcium carbonate has a wide range of uses:

As a raw material for the building materials industry (for the production of cement, quick-drying lime and limestone for building and road construction);

As a material for the steel industry;

As an abrasive and polishing agent in toothpaste

As a mineral fertilizer

As a mineral filler or coating for various industrial applications (paper, paint, slaked lime, plastics, carpets)
