Abstract

Metals are removed from lead alloys by treating the molten alloy with a flux consisting of lead fluoride and lead oxide, which may be in the proportions of a eutectic mixture, with or without lead sulphate. The lead oxide constituent of the flux may be formed in situ by adding to the bath a lead compound such as lead nitrate, or by blowing air into the bath. In carrying out the process, further lead oxide may be added to the flux when it thickens. The spent flux may be regenerated for re-use by reducing part of the contained oxides, or, if the reduction is carried out on the surface of a lead bath, the reduced metals enter the molten bath. The metals removed may include tin, antimony, arsenic, nickel, cadmium, zinc, magnesium, aluminium, alkali metals, and alkaline earth metals.
