    US4018877A - Production of calcium carbonate .

    Calcium carbonate is manufactured by the carbonation of an aqueous suspension of calcium hydroxide in the presence of a complex-forming agent for calcium ions which is added subsequently to the primary nucleation stage, and preferably during a first carbonation stage. Optionally there is also added a long-chain fatty acid or long-chain fatty acid salt, preferably after a final carbonation stage.

    Carbonatation - Wikipedia

    Carbonatation is a chemical reaction in which calcium hydroxide reacts with carbon dioxide and forms insoluble calcium carbonate : Ca (OH) 2 + CO 2 → CaCO 3 + H 2 O The process of forming a carbonate is sometimes referred to as " carbonation ", although this term usually refers to the process of dissolving carbon dioxide in water.
