re SOx levels In Raw mill

 This problem was solved many years ago   in other industries, for example, in the melting of copper. Sulfur in oxidation condition mainly flies in the form of a SO2 compound. This gas is post-burned to SO3 in catalytic reactors. After that, it is passed through the water and sulfuric acid (H2SO4) is produced either through the lime milk and get techno-gypsum  (CaSO4*2H2O).
