the quality of the end products Precipitated calcium carbonate produced with a prismatic and rhombohedralshape has maximum light dispersion at 04 to 05 µm sized particles while a scalenohedralshaped precipitated calcium carbonate has maximum light dispersion of 09 to 15 µm particles2 PCC of

Other calcium carbonate applications include its use in building construction plant and crop fertilizers food additives water and sewage treatment ceramics pharmaceuticals and cosmetics The process The following paragraphs describe a carbonization process for precipitated calcium carbonate PCC production from limestone Figure 1

According to the process limestone is burned at a high temperature to form calcium oxide and thereafter calcium carbonate is formed from calcium oxide in the presence of water and carbonate ions and the formed calcium carbonate is recovered The formation of the carbonate may be performed by carbonating calcium oxide with carbon dioxide gas in the presence of water or water vapour or by

Precipitated calcium carbonate PCC is conventionally produced through the gas–solid–liquid carbonation route which consists on bubbling gaseous CO2 through a concentrated calcium

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
