The contact of the lime slurry mists from atomizer wheels, or nozzle configurations, with sulfur dioxide in the flue gas stream causes a reaction to drop out the sulfur in the form of calcium sulfate (gypsum).

The chemistry of desulfurization The liquid used to "wash" the flue gas is a waterbased calcium solution. Limestone (CaCO3) is cheap and creates an alkaline environment in water:
Thus the main slag former in iron making is limestone, or dolomite rather than lime/dolomitic lime. There are however some smaller uses of lime in ironmaking: Iron ores are usually purchased as fines or as pellets. Iron ore pellets contain slagforming components, and are fed directly to the blast furnace.
The limestone contributes iron and aluminum (from clay minerals) to the FGD wastewater. Limestone is typically pulverized in a wet ball mill, and the erosion and corrosion of the balls contribute ...
