lime, which consists of the same ingredients as lime mud minus about 40 wt CO2 that has been released in the kiln. On a weight basis, reburned lime contains about 1.6 times more impurities than lime mud, and has a much higher sulphur content due to the sulphation reaction between lime mud and SO2 in the kiln gas.
