FIELD: metallurgy.
SUBSTANCE: extraction method of metal from slag containing this metal includes heating of liquefied metallic slag in the first furnace, implemented in the form of alternating-current electric furnace, and transfer of melt from the first furnace into the second furnace, implemented in the form of alternating-current electric furnace. Installation includes the first alternating-current electric furnace with submersible electrodes and the second alternating-current electric furnace with located horizontally in top and bottom field of melt by electrode plates, connected by means of melt transfer from one furnace into other, the second furnace is outfitted by electromagnets for providing of mixing of melt.
EFFECT: effectiveness increase of extraction process of metal from slag.
