Betterton-Kroll process, method widely used for removing bismuth from lead by adding calcium and magnesium to a molten lead-bismuth bath. Compounds are formed with bismuth that have higher melting points and lower densities than lead and thus can be separated as a solid dross. Bismuth may then be recovered from the calcium and magnesium by treatment with chlorine. …

The Betterton–Kroll process is an industrial process for removing bismuth from lead. Bismuth travels in crude lead bullion (which can contain up to 10% bismuth) through several stages of refining, until it is removed by the Kroll-Betterton process which separates the impurities as slag, or the electrolytic Betts process.

Calcium and magnesium are added to a molten lead-bismuth bath, the resulting bismuth compounds have higher melting points and lower densities than the lead, and can be removed as dross. The compounds are treated with chlorine to free up the bismuth. Temperature used in the process is about 380-500°C.
