FIELD: production of refined iron. SUBSTANCE: refined iron is produced from pressed material containing carbon reductant and ferric oxide. Pressed material is fed to molten-iron pool or to molten slag in such way that it floats on surface of molten-slag pool and larger part of pressed material is exposed to high-temperature gaseous atmosphere in furnace; molten-iron pool receives reduced iron generated by reduction of ferric oxide in pressed version. EFFECT: enhanced efficiency; simplification of method. 15 cl, 8 dwg
