The CaCO 3 may account for a composition as high as 98.5% or more in limestone, and when broken down, the value of CaO is 55.19%. Limestone, an impure form of calcium carbonate contains other constituents as impurities in addition to the carbon dioxide present. These are the calcium and magnesium silies as well as silies of iron, alumina, manganese, titanium, sodium and potassium.
