Sufficient care is necessary to investigate slag/metal partition of manganese when the manganese content of the hot metal is higher than the optimal content of hot metal normally used for oxygen steelmaking. The slag/metal partition of manganese estimated by using the manganate capacity concept and manganous oxide activity in slag. The obtained data showed that the partial molar enthalpy of solution of MnO in the converter slag is 151 k J mol-1 and the reaction of dissolution is endothermic. The calculated activity of MnO in the slag, by using the regular ionic solution model, is largely dependent on temperature and varies only slightly with the basicity. Both the manganate capacity and distribution ratio are mainly dependent on, and inversely proportional to temperature. Specifically, manganate capacity and distribution ratio decrease only slightly with increasing basicity. The calculated distribution ratios agree well with the actual data.
