  • Sulfur Removal By Adding Iron During The Digestion Process

    Jan 03, 2018 This paper proposes a novel approach to sulfur removal by adding iron during the digestion process. Iron can react with high-valence sulfur S 2 O 3 2, SO 3 2, SO 4 2 to generate S 2 at digestion temperature, and then S 2 enter red mud in the form of Na 3 FeS 3 to be removed. As iron dosage increases, high-valence sulfur concentration decreases, but the concentration of S 2 ...
