Abstract

Reducing the oxygen content of a copper melt comprises melting the copper initially in a shaft furnace, and subsequently feeding it to a treatment furnace via a transporting channel so that rinsing gas in the region of both the channel and the treatment furnace rises by flowing from the porous plugs. The rinsing gas containing 30-70% reduction gas and 70-30% inert gas flows from at least one of the plugs. The melt is electrically heated/moved in the treatment furnace. An independent claim is also included for an apparatus for reducing the oxygen content of a copper melt comprising a treatment furnace (1) having an inlet (2), a central part (12) and an outlet (3). Preferred Features: The reduction gas is provided with carbon monoxide, preferably carbon dioxide. The porous plug is made of Al2O3, SiC, SiO2 or MgO.
