The refining of lead by the Betts process | SpringerLink

Abstract. Current extractive metallurgy techniques for lead refining by the Betts Electrorefining Process (BEP) are reviewed. In the BEP, refined lead (>99.99%) can be produced by the electrorefining of impure lead anodes. The process relies on the selective dissolution of lead which leaves behind a strong and adherent layer of solids (slimes)...

Betts electrolytic process - Wikipedia

The Betts electrolytic process is an industrial process for purification of lead from bullion. Lead obtained from its ores is impure because lead is a good solvent for many metals. Often these impurities are tolerated, but the Betts electrolytic process is used when high purity lead is required, especially for bismuth-free lead.
