Calcium carbonate rocks are spread throughout the world, Which is why they have been among the most widely used
  • Only if the purity, degree of whiteness, thickness and homogeneity are acceptable is commercial extraction worthwhile. After quarrying, further treatment is required to process natural calcium carbonates of the highest quality, known generically as Ground Calcium Carbonate (GCC). Precipitated Calcium Carbonate (PCC) is a synthetic calcium carbonate produced industrially by means of a recarbonisation process. Both GCC or PCC can be used in a wide range of applications. For each end use there exists a tailor-made product where fineness and particle size distribution are optimally balanced to meet the technical demands of that particular requirement.

  • In these webpages, you’ll find information on CMHCO products including PCC, GCC quicklime, and hydrates lime.

    You’ll learn what they are, where and how they are used, and their contributions to the performance of our customers’ products. Included are guidelines to help you choose the right CMHCO’s product for a particular application.

  • Calcium Carbonate

    Calcium Carbonate is raw materials for more than 5000 years. and today we still use hundred of millions of tones of calcium carbonate in the building industry, in roads building industry and chemical industry.



  • However, although the deposits are plentiful, only a few are of sufficiently high quality to be worked and even a fewer number of deposits will provide raw materials for chemical industrial and agricultural uses other than the construction and roads building industry.
