  • Calcium Carbonate - Omya

    Calcium carbonate accounts for more than 4% of the earth's crust. As a result, the three minerals – calcite, aragonite and vaterite – are among the most important rock-forming minerals. Rocks are not the only deposits in nature – almost all stretches of water and countless plants and animals contain huge amounts of calcium carbonate as well.
