The manganese distribution ratios between CaO-SiO<SUB>2</SUB>-Fe<SUB><I>t</I></SUB>O-P<SUB>2</SUB>O<SUB>5</SUB> (≤0.9 mass%)-MnO (8-16 mass%) slags and liquid iron were determined at 1873 K in a MgO crucible. The activity coefficient of MnO and the values for <I>k</I><SUB>Mn</SUB>=(mass%MnO)/{[mass%Mn]·(mass%T.Fe)} and <I>C</I><SUB>Mn</SUB>=(mass%MnO)/{<I>a</I><SUB>Mn</SUB>·<I>a</I><SUB>O</SUB>} were formulated as functions of slag composition and temperature. By using these formulas, the manganese distribution ratios at 1623 and 1923 K were estimated as functions of total Fe content and (mass%CaO)/(mass%SiO<SUB>2</SUB>) ratio. The manganese contents in hot metal and steel were also estimated as functions of manganese distribution ratio, slag volume and amount of manganese ore by using the mass balance relation.
