Abstract
In a method for reducing metal-oxidic slags or glasses and/or degassing mineral melts, solid particles and/or melts are charged onto an at least partially inductively heated bed or column containing lumpy coke, and the reduced and/or degassed melt running off is collected. The device for reducing metal-oxidic slags or glasses and/or degassing mineral melts, which includes a charging opening (1) for solid or molten material and a tap opening (12) for the treated melt, is characterized by a tubular or channel-shaped housing (3) for the reception of lumpy coke (6), and a heating means surrounding the housing and including at least one induction coil (7, 8, 9).
