FIELD: non-ferrous metallurgy, in particular copper production.
SUBSTANCE: claimed method includes clinker caking with sulfide additive and melting with fluxing agent and iron dross, wherein trivalent iron in amount of 3-13 mass % is previously introduced into iron dross. Founding is carried out with oxygen consumption of 500-1100 nm3/t of clinker, and mass ratio of iron metal to trivalent iron in dross is maintained in range of 1-6.
EFFECT: simplified method of clinker reprocessing.
