A process for the production of precipitated calcium carbonate. A slurry of calcium hydroxide is agitated in a pressurized reactor, and carbon dioxide is provided under pressure to the reactor to produce precipitated calcium carbonate at a high reaction rate. Carbon dioxide is utilized at a high efficiency. Solubilized calcium ions and carbonate ions react to produce a calcium …
The carbonation reaction is a heterogeneous reaction occurring between the extracted calcium ions in the aqueous solution of ammonium salt and carbon dioxide gas, producing precipitated calcium carbonate (CaCO 3 ). (Eqs. (6), (7), (8), (9), (10), (11)) illustrate possible dissociation equations for dissolved CO 2 and precipitation of CaCO 3.
