  • Carbonate chemistry — Science Learning Hub

    Calcium carbonate has a very low solubility in pure water (15 mg/L at 25°C), but in rainwater saturated with carbon dioxide, its solubility increases due to the formation of more soluble calcium bicarbonate. Calcium carbonate is unusual in that its solubility increases as the temperature of the water decreases.

  • Precipitated Calcium Carbonate (PCC) | Minerals .

    Two reasons. First, there are several points in the PCC process where the calcium carbonate can be purified, removing much of the rock from the deposit that is not calcium carbonate—there are always some impurities in any limestone deposit. These include feldspar and other silicaceous minerals, as well as heavy metals.
