In the later case calcium carbonate is derived from the mixture, forming a grade of product called "precipitated calcium carbonate," or PCC. PCC has a very fine and controlled particle size, on the order of 2 microns in diameter, particularly useful in production of paper.
Apr 01, 2019· (a) Calcium carbonate (CaCO3, CAS Reg. No. 471341) is prepared by three common methods of manufacture: (1) As a byproduct in the "Lime soda process"; (2) By precipitation of calcium carbonate from calcium hydroxide in the "Carbonation process"; or (3) By precipitation of calcium carbonate from calcium chloride in the "Calcium chloride process".
Calcium carbonate is a commonly occurring mineral that is present in many rocks such as limestone and marble, as well as in the skeleton of stony corals, and is immensely versatile. In the construction industry, calcium carbonate is used as a raw material to produce lime cement and burnt lime or .

A method and apparatus for the production of calcium carbonate and calcium silicate in common superatmospheric reactors. Multiple reactors (T31, T32) can be provided for switching production between reactors, and advantageously utilizing process waste heat. On site production of both PCC and Calcium Silicate Hydrates is thus achieved in a paper mill.

Precipitated calcium carbonate (PCC) is produced by precipitating a calcium salt out of a solution under defined conditions. Normally, a filtered solution of calcium hydroxide Ca(OH)2 (from burnt lime) is used as the calcium source. This must not contain any colored impurities. Calcium carbonate is precipitated by the admixture of gaseous carbon dioxide or sodium carbonate Na2CO3.
