Calcium Carbonate Manufacturing Method

  • Cradle-to-gate life cycle assessment of precipitated .

    The main PCC production method is the so-called carbonation process, in which limestone (CaCO 3) is first calcined in a lime kiln to calcium oxide, slaked with water to calcium hydroxide, and then reacted with gaseous carbon dioxide to calcium carbonate.

  • Calcium carbonate - Wikipedia

    Calcium carbonate is the active ingredient in agricultural lime and is created when calcium ions in hard water react with carbonate ions to create limescale. It is medicinally used as a calcium supplement or as an antacid, but excessive consumption can be hazardous.
