How Calcium Carbonate is

Calcium carbonate is divided into two industrial categories: Ground Calcium Carbonate (GCC) and precipitated calcium carbonate (PCC). The two categories use different manufacturing methods. GCC is manufactured by physically grinding and classifying limestone. PCC is manufactured through chemical synthesis using limestone as a raw material.
