The invention relates to ferrous and non-ferrous metallurgy and can be used at refinement and utilization of metallurgical slags. A method for refinement of metallurgical slags comprises the dioxidation of iron and magnetite with blowing of final liquid slag by oxygen-containing gas (oxygen or air) with intensity of 0.001-10 m/minute·t of the slag, which allows the use of magnetic separation of obtained materials for their further separate use.
