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.
