The invention relates to a continuous method of removing tin from lead. The method comprises maintaining a pool of molten lead at a temperature of from 510 DEG C. to 570 DEG C., introducing molten lead into the pool, injecting chlorine and oxygen into the molten lead in an amount to react with tin present as an impurity in the lead to form a tin-containing dross and then separating the lead from the dross. Separation may either be performed in the reaction vessel itself or in a separate settlement vessel. |
