In nature, calcite or calcium carbonate is mostly found as limestone. It is used for vast industrial purposes and is extracted by mining or quarrying. Industrially, it can be prepared as PCC—Precipitated Calcium carbonate—a very fine and controlled particle size, on the order of 2 microns in diameter, particularly useful in the production of paper.

Carbonate minerals are extremely varied and ubiquitous in chemically precipitated sedimentary rock. The most common are calcite or calcium carbonate, CaCO 3, the chief constituent of limestone (as well as the main component of mollusc shells and coral skeletons); dolomite, a calcium-magnesium carbonate CaMg(CO 3 ) 2 ; and siderite, or iron (II) carbonate, FeCO 3, an important iron ore .
