  • Process for reducing nonferrous metal oxides in slags
    Patent number: 5246484
    Abstract: In the reduction of liquid slags or molten salts which contain nonferrous metal oxides and are disposed over a liquid metal layer consisting of the corresponding nonferrous metal oxides and are disposed over a liquid metal layer consisting of the corresponding nonferrous metal, carbonaceous reducing agents and oxygen-containing gas are injected through nozzles into the metal layer. In order to improve the gasification of the reducing agent the height of the metal layer is so selected that at least 50% of the reducing agent are reacted to CO and optionally H.sub.2 in the metal layer before the reducing agent enters the slag layer.
