FIELD: metallurgy.
SUBSTANCE: method of reduction and/or refining metal containing slag consists in supplying calcium carbide as reducer to slag in furnace. Also calcium carbide is supplied at volume determined in dependence on magnetite and/or copper oxide (I) contents in slag to facilitate growth of temperature at the boundary between slag and carbide and for change of slag structure to accelerate the rate of reaction.
EFFECT: intensification of reduction process and increased efficiency.
