Calcium carbonate has the chemical formula CaCO3. In nature, marble, limestone and chalk contain calcium carbonate. By processing calcium carbonate from marble, one obtains precipitated calcium carbonate, which is ground into a powder called ground calcium carbonate. Ground calcium carbonate has many industrial, medicinal and pharmaceutical uses.
