Abstract
An electrorefining process is disclosed for producing high purity tin having reduced short-term and long-term alpha particle emissions and reduced lead levels. The process may use a mixed acidic electrolytic solution including at least a first electrolyte that provides sulfate ions in the mixed electrolytic solution, such as sulfuric acid, and a second electrolyte that provides halide ions in the mixed electrolytic solution, such as hydrochloric acid.
