Betts process
metallurgy
Quick Summary
The Betts process is an electrolytic process used for refining lead. In this method, lead is purified by electrolysis, where the crude metal acts as the anode and dissolves into an electrolyte solution. The pure lead is then deposited onto the cathode. The specific electrolyte used in the Betts process is a solution of lead fluosilicate (PbSiF6) and fluosilicic acid. This technique was developed by Anson G. Betts, an American metallurgist.12
