Preparation of Calcium Carbonate CaCO 3 Calcium carbonate is primarily mined and processed from diverse natural mineral sources. It can also be made chemically by combining quicklime (calcium oxide, CaO) with water to produce calcium hydroxide (Ca(OH) 2 ), which is then treated with carbon dioxide to form the calcium carbonate salt.
