Desilvered lead is freed of bismuth according to the Betterton-Kroll process by treating it with metallic calcium and magnesium, which forms a bismuth dross that can be skimmed off. Very pure lead can be obtained by processing smelted lead electrolytically by means of the Betts process. The process uses anodes of impure lead and cathodes of ...

Bismuth trioxide (Bi2O3) is the prevalent commercial oxide of bismuth. A precursor to the preparation of other compounds of bismuth, including the chemical reagents, bismuth trioxide has specialized uses in optical glass, flame-retardant paper, and, increasingly, in glaze formulations where it substitutes for lead oxides. In the last decade, bismuth trioxide has also become a key ingredient in ...

The Betterton-Kroll process is used to remove these impurities. In the process, calcium and magnesium are added to the molten lead at temperatures around 380 °C. The calcium and magnesium react with the bismuth and antimony in the bullion to form alloys with a higher melting point, which then can be skimmed off of the surface.
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.

The Betterton-Kroll process begins by heating lead bullion to around 500 °C. A calcium-magnesium alloy is added to the solution, which melts into the bullion in 15-20 minutes. The lead mixture is then cooled to the liquidus point (the lowest temperature that the alloy is completely liquid), which around 320-380 °C.

The results of tests to examine the Betterton-Kroll 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.

Similarly to how the Parkes Process removes silver from lead, the Betterton-Kroll process removes bismuth from the lead. It was first developed in the 1920s but was later refined in the 1930s. This is when a substance contains both lead and bismuth. It requires professionals to add magnesium and calcium to the concoction.
