  • Patent number: 6289034
    Abstract: A process for producing metals from a metalliferous feed material in an electric furnace is disclosed. The process includes the steps of forming a molten bath having a metal layer and a slag layer on the metal layer in the furnace and supplying electrical energy to the furnace and converting the electrical energy to thermal energy and thereby contributing to the heat input requirements of the process. The process also includes injecting a carrier gas and a solid carbonaceous material into the molten bath via one or more than one solids injection lance/tuyere and causing molten material to be projected from the molten bath as splashes, droplets, and streams into a space above a nominal quiescent surface of the molten bath and forming a transition zone.
