This report presents the economics of Precipitated Calcium Carbonate PCC production from lime and sodium carbonate in the United States, via a conventional lime-soda process. In this process, calcium hydroxide is generated by treating lime with water. Then, calcium hydroxide reacts with soda ash.
Commercially, calcium carbonate is available in two types - precipitated calcium carbonate PCC and ground calcium carbonate GCC. Calcium carbonate is majorly used as a filler or a pigment in paper, plastic, and paints amp coatings, and also as a dietary supplement in food and healthcare industries.
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 CaOH2 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.
The precipitated calcium carbonate obtainable by the process according to the present invention may be characterized by a specific particle size distribution. In one embodiment, the precipitated calcium carbonate has a d 50 ranging from 0.1 to 10.0 m, preferably from 0.2 to 5.0 m, and more preferably from 0.3 to 3.0 m.
Calcium carbonate manufacturing process Posted 2020-01-07. Calcium carbonate is usually divided into heavy calcium carbonate ground calcium carbonate powder and light calcium carbonate precipitated calcium carbonate. Heavy calcium carbonate is also called ground calcium carbonate, referred to as heavy calcium carbonate ground calcium carbonate powder, which is produced by
Calcium carbonate includes natural fine,ground calcium carbonate FGCC produced from limestone, marble, and chalk deposits, and precipitated calcium carbonate PCC, also referred to as synthetic or light calcium carbonate. This report covers the markets that consume fine grades of calcium carbonate, generally less than 67 micron particle size.

A process for producing rhombic or barrel shaped precipitated calcium carbonate. Quicklime is slaked in an aqueous solution containing about 0.1 to about 2 by weight of a sugar, based upon the weight of the CaCO 3 to be produced. Carbon dioxide is added to the slaked lime slurry at a preferred temperature of about 50 F.-70 F. until the pH drops from about 11-12 to about 7-8.
The global calcium carbonate ground and precipitated market is continuing to expand even though the rate of growth has slowed in recent years. Growth in China has been the main driver of the increase in overall global consumption but slowed from an estimated 22Mt in 2012 to 27Mt in 2015.
