FIELD: metallurgy.
SUBSTANCE: molten slag is brought into contact with mixture of oxide and carbon-containing materials; mixture is heated with molten slag heat and oxide materials are recovered. At that, mass of mixture of oxide and carbon-containing materials is not more than the half of molten slag mass. Carbon content in mixture of oxide and carbon-containing materials is 10-30 wt %.
EFFECT: invention allows utilising molten slag heat and recovering oxide materials.
