Manufacturing Process ROLAIDS

Calcium carbonate Calcium carbonate, as it is used for industrial purposes, is extracted by mining or quarrying. Pure calcium carbonate can be produced from marble, or limestone. It can also be prepared by passing carbon dioxide into a solution of calcium hydroxide, forming "precipitated calcium carbonate," or PC C (ima-na, 2021)

Fine Calcium Carbonate Production by CO2 Mineralization of

Abstract. Calcium carbonate production via CO2 mineralization offers an attractive route for carbon capture and utilization. The process sequesters CO2 in a stable form of fine precipitated calcium carbonate, a high-value product with unit price in the range of $230-$280/t and a global market projected to reach 99 M tons in 2021.
