  • USE OF ALKALINE CARBONATE SALTS TO REDUCE THE DOSE OF ACRYLIC POLYMER IN A METHOD OF GRINDING CALCIUM CARBONATE IN WATER
    Publication number: 20120142842
    Abstract: The use of alkaline carbonate salts in a method of manufacturing an aqueous composition of calcium carbonate by grinding. These salts make it possible to reduce the quantity of grinding aid agents implemented, which are water-soluble homopolymers or copolymers of acrylic acid. These homopolymers or copolymers greatly contribute to increasing the carbon dioxide content of the atmosphere, and are derived from raw materials that come from a fossil fuel: by limiting their quantity, both the environment and our natural resources are preserved.
