— Carbonate. Calcium carbonate (CaCO 3) is a common substance found in rock in all parts of the world, and is the main component of shells of marine organisms, snails, pearls, and eggshells.Calcium carbonate is usually the principal cause of hard water. Most calcium carbonate used is extracted by quarrying or mining.
