METHOD OF CONTINUOUS OR PERIODICAL RECEIVING OF METAL OR SEVERAL METALS FROM SLAG, CONTAINING SPECIFIED METAL OR COMPOUND OF SPECIFIED METAL

摘要

FIELD: metallurgy.;SUBSTANCE: invention elates to method of continuous or periodic receiving of metal or several metals from slag, containing specified metal or compound of specified metal. Method includes heating and melting of liquid metallic slag in primary or secondary melting mill, implemented in the form of electric furnace of alternating current. From primary or secondary melting mill melt of slag is fed into electric furnace of direct current. In this furnace it is implemented electrolytic deposition of extracted metal. Additionally into primary or secondary melting mill it is fed and/or injected restorative in the form of silicocalcium (CaSi), calcium carbide (CaC₂), ferrosilicon (FeSi), aluminium (Al) and/or gaseous restorative.;EFFECT: effectiveness increase of slag cleaning of metals extraction from slag.;12 cl, 2 dwg, 1 ex
