To Limestone To Pure Calcium Carbonate Process

Calcium carbonate is the principal constituent of limestone (a sedimentary rock) and its pure state is obtained in three steps by the calcination of limestone and subsequent reaction with water and carbon dioxide. ca this is important when water is used for industrial process or cleaning purposes.
