  • Method of producing metals and metal alloys
    Patent number: 6267799
    Abstract: A method and an apparatus for producing metals and metal alloys from metal oxides in a metallurgical vessel containing a molten bath having a metal layer and a slag layer is disclosed. The method is characterized by injecting a carrier gas and a solid carbonaceous material and/or metal oxides into the molten bath from a side of the vessel that is in contact with the molten bath or from above the molten bath so that the solids penetrate the molten bath and cause molten metal to be projected into the gas space above the molten bath to form a transition zone. The method is also characterized by injecting an oxygen-containing gas into the gas space to post-combust reaction gases released from the molten bath into the transition zone.
