Calcium carbonate is used in the purification and separation of iron from its ore. It is often used in swimming pools for maintaining the alkalinity of water and countervailing acidic properties of the disinfectant. As it is heavy, calcium carbonate increases the density of drilling fluids and helps in controlling the down hole pressure. Hence it is widely used in the oil industry.
