WebJun 1, 2011 · One of the most common causes of CaSO 4 scale formation in hydrometallurgical processes is the transformation of the metastable CaSO 4 hydrate to the stable one (usually gypsum to anhydrite), as was the case with the Bulong nickel/cobalt plant ( Nofal et al., 2001 ). WebGypsum is speculated to promote the rapid hydration of steel slag to form ettringite (C_3A.3CaSO_4.32H_2O), which then reacts with CO_2 to produce monocarbonate; thus, gypsum plays a catalytic role in this system. The results of this study therefore provide theoretical guidance for the preparation of steel slag-gypsum carbide building materials.
