  • Coating Calcium Carbonate with Stearate Bepex

    Problem: Calcium Carbonate is a commonly used filler in plastics compounding.Typically, a stearate coating is required to improve dispersiblity of this additive into the compounding process. Traditional coating processes can form undesirable agglomerates that increase the amount of additive required. Due to the high costs of stearates, companies looked for an effective, continuous coating

  • Calcium Carbonate an overview ScienceDirect Topics

    Calcium carbonate (CaCO 3) is a substance widely used for various purposes, for example, as a filler and pigment material not only in paper, plastics, rubbers, paints, and inks but also in pharmaceutics, cosmetics, construction materials, and asphalts and as a nutritional supplement in animal foods (1).Besides the so-called ground calcium carbonate (GCC), which is milled from natural limestone

  • Application of Calcium Carbonate in Plastics and FAQs

  • Ground Calcium Carbonate Ore Mineralogy Processing

    With dry processing, the entire stone, including the impurities, is ground into product. Wet processing, in contrast, offers the opportunity to improve the purity of the products by a reverse froth flotation process. The reverse flotation process removes the impurities, usually highly colored, from the carbonate ore as a froth.
