known to chemists as calcium carbonate, small amounts of clay, silt, chert (silica, SiO 2), and dolomite (calcium-magnesium carbonate, CaMg[CO 3] 2).2 To be called limestone, the rock has to have a composition of over 50% dolomite and calcite, though the exact percentages vary widely. The limestone available commercially is over 80% calcite and,Calculating CO2 Emissions from the Production of Lime,,refining and precipitated calcium carbonate production. High-calcium limes are derived from limestone that contain 0 to 5 percent by weight of magnesium oxide, and thus have a proportionally high calcium content. In contrast, dolomitic limes are usually 35 to 45 percent magnesium oxide. Hydraulic limes undergo partial hardeningThe Value of Agricultural Limestone,reported in a soil test is in tons of pure calcium carbonate, not tons of any liming material. The TNV is the percentage of the limestone capable of neutralizing an acid and is expressed as CCE. If a limestone has a TNV of 80 percent it means that 1 pound of it will neutralize the same amount of acid as 0.8 pound of pure calcium carbonate.
