Experimental investigation of fundamental viscosity, density, and leaching characteristics of sodium-iron-silicate slags
Environmental regulations govern the emission of sulfur dioxide for lead smelters. Because of this, some have adopted a hydrometallurgical desulfurization step, which results in a sodium-iron-silicate slag being generated in their furnaces. This slag must be disposed of, but the behavior of impurities from the solidified slag and the physical properties of the molten phase are not well understood. In this work, the leaching characteristics, viscosity, and density of a sodium-iron-silicate system representing a modern secondary lead smelter’s slag have been studied. Slag viscosity increased with ...
