Abstract
A process of treating a solid material containing lead and elemental sulphur, by feeding the solid material to a furnace containing a bath of molten slag under conditions such that elemental sulphur burns in the furnace to form sulphur dioxide and lead in the solid material is oxidized and reports to the slag, then removing a gas stream containing sulphur dioxide from the furnace, and finally removing a lead-containing slag from the furnace.
