Calcium Carbonate is a chemical compound with the chemical formula CaCO₃ that is found naturally in rocks and minerals such as limestone, marble and calcite. This substance is an inorganic and colorless salt and exists in nature in the form of white crystals. Calcium carbonate is divided into two main types:
Natural calcium carbonate: occurs naturally in nature and is usually extracted from sources such as limestone, marble, and calcite.
Precipitated calcium carbonate: It is produced through chemical processes in laboratories or industry and is usually of higher purity.
