FIELD: metallurgy.
SUBSTANCE: in method it is implemented preparation of charge, including introduction of carbon and flux, loading of charge into furnace on liquid metallic bath with simultaneous feeding of natural gas, oxygen and air, heating, charge melting and reduction by carbon monoxide of oxides, thermodynamic strength of which is lower than manganese protoxide has, with receiving of metallic melt and melt, containing manganous oxides and oxides, thermodynamic strength of which is higher than manganese protoxide has, with viscosity in the range 0.3-10 poise, yield of metallic melt from furnace, directing of oxide melt to heated up to temperature 1850-2200°C carbonaceous reductant, and reduction of oxides up to receiving of melt of required composition.
EFFECT: invention provides reprocessing of bases and concentrates, and receiving of extraction of leading element from rerolling manganese slag.
