FIELD: metallurgy.
SUBSTANCE: invention concerns pyrometallurgy and can be used for utilisation of fine-dispersed oil dross. Method of metal extraction from oil dross includes reducing fusion in reactionary capacity of electric furnace with carbonaceous restorative and removing of forming metal alloy from electric furnace. At that before melting oil dross is heated in pipe furnace by heat of effluent gases from melting electric furnace till the temperature 600-800°C for burning of gaseous products of pyrolysis and forming of solid carbon residue, used in the capacity of additional restorative during melting. Melting is implemented in ore-thermal conditions, formed on the basis of fluorite melt.
EFFECT: creating of simple and inexpensive method and reduction of restorative consumption.
