Abstract (en)
[origin: WO2009076945A1] The invention relates to a device for extracting metals or metal compounds from a material containing the metal or the metal compound, with a furnace vessel (2), with a first inlet for supplying the material, a first outlet (10) for discharging exhaust gas, one or more electrodes (1) for melting and/or reducing the material supplied, which protrude into the furnace vessel, with a bottom electrode (5) formed as a cathode, a space (16) provided in the region of the slag tap hole (12) and serving as a settling zone, with an electromagnet or permanent magnet (6), which is placed in the furnace vessel in such a way that a DC current flow produced in the furnace vessel is crossed by the magnetic field, and also a tap hole (8) for removing the molten metal or the metal compound and an overflow or tap hole (12) for the slag.
