About Calcium Carbonate. Calcium Carbonate (a.k.a. CaCO3) is a non-toxic and odorless inorganic salt, commonly found as a white mineral (calcite) which occurs naturally in chalks, limestones and marbles. These rocks are classified as limestones, a general term used for a rock containing varying proportions of calcite and dolomite. In nature, it can also be found as the main component of shells, pearls and eggs. The quality of Calcium Carbonate depends on some factors: purity, whiteness, homogeneity, and thickness. Calcium carbonate is a very versatile mineral filler and has in a wide variety of applications.

Commercial Grades. precipitated calcium carbonate (PCC, smaller, more pure crystals) and ground calcium carbonate (GCC, bigger, less pure crystals).

Uses. Calcium Carbonate is largely employed in the pulp and paper industry. It can be used as a filler and pigment, making possible the production of a whiter, higher quality pigment than other minerals. In the construction industry, Calcium Carbonate is used as a filler in concrete, increasing its durability and appearance, and to purify metals for use in construction applications. Other application of Calcium Carbonate is in fertilizers, to provide calcium to plants and pH stabilization of the soil. Calcium Carbonate can also be an additive to food products for livestock animals and humans, and a as supplement in vitamins. Calcium Carbonate is employed in the removal of acidity and impurities in water and sewer treatment plants. Finally, it can be found in some amount in several other products, like glass, ceramics, chalk, pharmaceuticals, and cosmetics. It also works as a plasticizer, sulfur dioxide remover and oral care agent.
