Ground Calcium Carbonate Ore Mineralogy Processing

Mineralogy Calcite, CaCO3, is the principal mineral in GCC. Pure calcite is soft (3 on mohs scale), is white, has a specific gravity of 2.71, and has a refractive index from 1.486 to 1.658. Several elements can substitute for calcium and change its hardness, specific gravity, and optical properties. Prominent among these are Mg, Fe and Mn.

What Is Calcium Carbonate Used For? | Reference.com

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.
