  • How Calcium Carbonate is

    Calcium carbonate is divided into two industrial egories: Ground Calcium Carbonate (GCC) and precipitated calcium carbonate (PCC). The two egories 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.

    However the production of reactive calcium from limestone usually generates an amount of CO 2 equal to or larger than what is chemically stored in carbonates (1). Thus in case calcium could be brought into a PCC manufacturing process with a smaller carbon dioxide penalty the process route would contribute to mitigating CO 2 emissions and

  • Lime Production: Industry Profile

    Limestone can be egorized as either high calcium or dolomitic. Pure high-calcium limestone is 100 percent calcium carbonate (100 percent calcite or aragonite). Generally limestone of this purity does not occur naturally. High-quality high-calcium limestone would actually contain 97 to 99 percent calcium carbonate and 1 to 3 percent impurities.
