Precipitated calcium carbonate (PCC) is an innovative product derived from lime, which has many industrial applications. PCC is made by hydrating high-calcium quicklime and then reacting the resulting slurry, or "milk-of-lime", with carbon dioxide. The resulting product is extremely white and typically has a uniform narrow particle size distribution, PCC is well established as a […]

Precipitated Calcium Carbonate is produced as a result of 4 key steps: Calcination (H2): Limestone is heated at about 1000 degree centigrade in a kiln to produce quick lime. Hydration/slacking (H2): The quick lime is in a pebble for mat at this time. It is mixed with water to form a hydrated lime slurry…

Arthur L. Kohl, Richard B. Nielsen, in Gas Purification (Fifth Edition), 1997 Process Description. The overall effects of the double alkali process are identical to those of the limestone/ lime slurry processes—SO 2 is removed from the gas, lime or limestone is consumed, and a calcium sulfite or sulfate by-product is produced. The intermediate steps, however, are quite different and result ...
