Abstract
The U.S. Bureau of Mines evaluated the potential of using simplistic methodologies to convert waste battery acid containing 300 to 2,000 ppm metal ions into recyclable products. Several recycling approaches tested, including ion adsorption, ion exchange, and solvent extraction, were not successful in producing battery-grade acid due to metallic impurities in the waste acid that were extremely difficult to remove. Waste acid samples contained metal ions that were common to those associated with brass flue dust, another waste material. The recycling potential of the waste acid was significantly improved by utilization of the waste acid, instead of virgin sulfuric acid, to extract zn from the brass flue dust. The waste acid was also utilized to extract cu and cd from sludge wastes. Several neutralization schemes designed to reduce the quantity of hazardous sludge generated were also evaluated as alternatives to the conventional lime-neutralization process.
