Details: Calcium Carbonate contains one of the highest concentrations of elemental calcium (about 40%). Calcium carbonate is a chemical compound, represented by the chemical formula CaCO3. It is estimated that about 4 percent of the Earth’s crust is made up of calcium carbonate. It is found naturally in the form of minerals and rocks, some of which include calcite, limestone, chalk, marble, and aragonite. Calcium carbonate is the active ingredient in agricultural lime, and is created when calcium ions in hard water react with carbonate ions creating limescale.
