FIELD: metallurgy.
SUBSTANCE: invention relates to ferrous metallurgy, namely to a charge for smelting pig iron in a blast furnace. Composition of the ore portion of the charge for smelting pig iron in the blast furnace includes iron-containing raw materials, manganese-containing raw materials and limestone, and further includes a slag of silicothermal smelting of metallic manganese.
EFFECT: reduced specific consumption of manganese-containing raw materials and limestone, the useful use of manganese from slag of silicothermal smelting of metallic manganese, improved environmental situation in the area of the metallurgical plant, smelting metallic manganese silicothermically.
