Abstract
In a process for the de-sulphurization and de-gasification of copper, melted copper, possibly after a preliminary oxidation-reduction process is treated by an agent consisting of a hydroxide of an alkaline or alkaline earth metal, or of a mixture of such hydroxides, preferably caustic soda. The treatment may be continuous, as by causing the molten copper to flow from the furnace through a layer of the salt.
