Abstract. Calcium carbonate (CaCO 3) is an important inorganic mineral in biological and geological systems. Traditionally, it is widely used in plastics, papermaking, ink, building materials, textiles, cosmetics, and food. Over the last decade, there has

The vast majority of calcium carbonate used in industry is extracted by mining or quarrying. Pure calcium carbonate (such as for food or pharmaceutical use), can be produced from a pure quarried source (usually marble). Alternatively, calcium carbonate is prepared from calcium oxide. Water is added to give calcium hydroxide then carbon dioxide is passed through this solution to precipitate the desired calcium c

However, the production of reactive calcium from limestone usually generates an amount of CO 2 equal to or larger than what is chemically stored in carbonates (1). Thus, in case calcium could be brought into a PCC manufacturing process with a smaller carbon dioxide penalty, the process route would contribute to mitigating CO 2 emissions and global

An attractive product for the mineral carbonation process is the precipitated calcium carbonate (PCC). Production of PCC through the carbonation route has attracted the attention of researchers for several years. This is due to its large ability to capture and store large amounts of carbon dioxide [4].
