• Mineral Precipitation

     · Common mineral cements include silica (quartz), calcite, limonite, hematite, and clay minerals. Biological activity in the oceans causes calcite (calcium carbonate) to precipitate through processes involving excretion and precipitation. Carbonate sediments can accumulate as reefs, stromatolites, or lime mud derived from the reworking of limey ...

    Precipitated Calcium Carbonate. PCC stands for Precipitated Calcium Carbonate—also known as purified, refined or synthetic calcium carbonate. It has the same chemical formula as other types of calcium carbonate, such as limestone, marble and chalk: CaCO3. The calcium, carbon and oxygen atoms can arrange themselves in three different ways, to form three different calcium carbonate minerals.
