Caco3 Carbonate Calcium Used Production

  • Calcium carbonate, characteristics, properties and

    06/10/2019· Chemical reactions of calcium carbonate: Calcium carbonate is the average salt formed by strong base (calcium hydroxide Ca (OH)2) and weak acid (carbonic acid H2CO3). Aqueous solutions of CaCO3 have a weak alkaline reaction. Chemical properties of potassium hydroxide are similar to the properties of the carbonates of other metals.

  • 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.
