— Calcium carbonate is a soft mineral with a Mohs hardness of 3. Since ground calcium carbonate is a naturally mined material, impurities are present as they are in all ore bodies. Almost all contain some dolomite (CaMg(CO3)2) with a Mohs of 4, while others contain mica (Mohs 3) or graphite (Mohs 1-2).
