Analysis of the Kroll-Betterton Process: The Removal of ...

AbstractThe results of tests to examine the Kroll-Betterton process for the removal of bismuth from lead bullion using calcium and magnesium are presented. The ratio of the masses of the two metals may be optimized to achieve minimum process cost. Losses of the metals in the process are attributed mainly to attrition during dissolution in the bullion.

Betterton-Kroll process | metallurgy | Britannica

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.

Bismuth - Wikipedia

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.
