Removal of sulfur by adding zinc during the digestion process of high-sulfur bauxite


This paper proposes a novel approach to sulfur removal by adding zinc during the digestion process. The effects of zinc dosage on the concentrations of different valence sulfur in sodium aluminate solution were investigated at length to find that high-valence sulfur (S2O3 2−, SO3 2−, SO4 2−) concentration in sodium aluminate solution decreases, but the… (More)
