Abstract
Sulfuric-acid leaching was used to extract metals from an arsenic- containing flue dust waste material. Temperature, percent solids, and acid concentration were the leach parameters examined in this U.S. Bureau of Mines study. Arsenic, cadmium, copper, and zinc were soluble under all leach conditions, and arsenic, copper, iron, and molybdenum extractions increased with increasing acid concentration. Oxidizing conditions, achieved with hydrogen peroxide additions, increased the extraction of copper. Leaching was also carried out using a refinery bleed waste solution, which was determined to be a viable source of sulfuric acid. Coprocessing the flue dust with bleed electrolyte provides a treatment option for utilization and disposal of both wastes.
