Description:
The heavy calcium carbonate is a white powder made of fine calcite which got through selecting, washing,  air-drying, crushing, grinding, filtration process etc. The products characteristic is high whiteness and purity, soft colour and stability in chemical composition, therefore it is a special filliing which widely used in industry.
