Ground Calcium Carbonate (GCC)

Chemical name : Calcium Carbonate

Chemical formula : CaCO3

Limestone, which is primarily calcium carbonate, is a sedimentary rock made from the minerals calcite or aragonite.  A large portion of limestone is made from the skeletal remains of sea creatures and organisms.  Ground Calcium Carbonate (GCC) differs from Precipitated Calcium Carbonate (PCC) in that the GCC is formed directly from grinding limestone rock into a powder, while PCC is chemically produced and precipitated out as powder.
