ABSTRACT:
A process and apparatus for producing a copper metal or alloy wherein a first material is added to a molten metal, consisting essentially of copper preferably in a furnace. After the first material is added, the molten metal is passed through a filtration device to remove particulate matter from the molten metal and/or reduce the oxygen content of the molten metal. After filtration, a second material is added to the molten metal.
