FIELD: metallurgy.
SUBSTANCE: metallic iron concentrate, containing nonferrous and precious metals is melted at the temperature 1400-1600°C with feeding of oxygen-containing wind and not containing flux silicon with forming of metal melt and wustite dross. 70-95% of iron is transferred into the wustite dross, containing less then 5-10% SiO2, and nonferrous and precious metals - into metallic melt with following divided discharge of melt products.
EFFECT: invention provides transferring of major mass of iron into the wustite dross, and nonferrous and precious metals to concentrate in metal alloy, available for further inclusion into the technology of copper-nickel manufacturing.
