This study conducts the substance flow analysis (SFA) of Manganese (Mn) with regard to the iron and steel cycle, which accounts for 95% of the demand for Mn, along with the data collection and assessment of material/substance flow; as a result, an efficient material cycle system is formulated for the Mn flow.The main conclusions are (1) Mn charged as iron ore and the Mn content of other ferrous raw materials reached 266.2×103 t-Mn of which 208.9×103 t-Mn was discharged as pig iron and 55.4×103 t-Mn as blast furnace slag in the ironmaking process, and (2) 530.7×103 t-Mn was discharged as steelmaking slag and 577.6×103 t-Mn was charged in the secondary refining process as Ferro-Mn, Si–Mn, and metal Mn for the purpose of adding them as constituents of alloy in the steelmaking process.
