  • Precipitated Calcium Carbonate (PCC) Minerals

    Precipitated Calcium Carbonate. PCC stands for Precipitated Calcium Carbonate—also known as purified, refined or synthetic calcium carbonate. In 1898, a new factory was built in Birmingham using the milk of lime process, which is described in more detail below. This PCC operation is now part of the Performance Minerals group of SMI.
