Ground Calcium Carbonate (GCC) differs from Precipitated Calcium Carbonate (PCC) in that the GCC is formed directly from grinding limestone rock into a powder, while PCC is chemically produced and precipitated out as powder. Pure calcium carbonate is a relatively soft mineral/compound, with a Mohs hardness of 2.5 – 3.0.
