Research Abstract

The equilibrium distribution of Mn and Fe between Fe-Mn-Ca-S-O system and FeO-MnO-CaO-SiO2-MgO-P2O5 slag was determined under the controlled partial pressure of oxygen and sulfur at 1673K. It was found that phousphorus was not distributed to the matte in equilibrium with the molten slag. The effects of slag compositions, temperature, and oxygen and sulfur potential in gas phase on the distribution behavior of manganese and iron between the matte and slag were experimentally examined. It was also found dissolution behavior of (C2S-C3P)ss in water depended on the C3P ratio and mineral phase in sample. From these results, fundamental technique has been established to obtain manganese through sulfurization of the steelmaking slags.
