Synthesis of high-purity precipitated calcium

2015-12-1  In this study, we used the insight gained from our previous work and developed an indirect aqueous CaS carbonation process for the production of high-grade CaCO 3 (i.e. >99 mass% as CaCO 3) or precipitated calcium carbonate (PCC). The process used an acid gas (H 2 S) to improve the aqueous dissolution of CaS, which is otherwise poorly soluble. The carbonate product was primarily calcite

Precipitated Calcium Carbonate – Multifunctional

Precipitated calcium carbonate is produced using the most economic process existing today. Limestone is converted into calcium oxide and carbon dioxide by means of calcination at temperatures in excess of 900°C. To ensure a high level of purity, the calcination process is carried out using natural gas.
