FIELD: metallurgy.
SUBSTANCE: invention relates to metallurgy, in particular to a method for processing waste dust from metallurgical production. Proposed method comprises feeding dusty wastes from metallurgical production with carbon material on surface of molten slag in slag receiving bowl after filling with liquid slag of melting unit, heating, reduction of metal oxides and extraction of recovered metals. Layer of dusty wastes is placed between layers of carbon material. Extraction of recovered metals is performed by magnetic separation when processing slag.
EFFECT: use of invention prevents ambient secondary metal oxidation of reduced oxygen and provides clean metallic bars.
