FIELD: metallurgy.
SUBSTANCE: present invention relates to a method for extracting metal from metal-bearing slag, in which the metal-bearing slag is heated with mixing in at least one reactor and in which the liquid slag in a reactor is periodically mixed by an appropriately directed magnetic field by switching on and off the magnetic field over the course of 5 seconds to 10 minutes. Reactor with mixing is a reduction furnace with a variable magnetic field, preferably a direct current electric furnace, most preferably a reactor in the form of a melting chute or ladle. Displayed here is a device for extracting metal from metal-bearing slag, including a reactor with mixing for heating the metal-bearing slag and an electromagnet to induce a magnetic field in such a way that liquid slag is mixed, wherein a switching device is provided for periodic operation of the electromagnet.
EFFECT: higher degree of metal extraction from metal-bearing slag is provided.
