Calcium carbonate is used either in its naturally occurring state or in the pure form. Pure calcium carbonate is extracted from natural sources by various techniques such as mining and quarrying. At present, calcium carbonate used is widely used for multiple functions, including as a mineral filler, whitening agent, and an alkalizing agent.
