摘要： 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.

摘要： A method for purifying tin includes exposing an electrolytic solution comprising tin to an ion exchange resin and depositing electrorefined tin from the electrolytic solution. The deposited electrorefined tin has alpha particle emissions of less than about 0.01 counts/hour/cm2 immediately after the deposition step, and an alpha emissivity of less than about 0.01 counts/hour/cm2 at least 90 days after the deposition step.
