Preparation: Calcium carbonate is mainly obtained from its various natural mineral sources by mining and processing. It is also prepared by chemical synthesis by reacting quicklime (calcium oxide, CaO) with water to give calcium hydroxide (Ca(OH) 2), which is then treated with carbon dioxide to precipitate the calcium carbonate salt.
