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.

在1673K的可控氧硫分压条件下，测定了Fe-Mn- ca - s - o体系和FeO-MnO-CaO-SiO2-MgO-P2O5渣中Mn和Fe的平衡分布。结果表明，磷与熔渣在平衡状态下并没有分布到冰粉中。实验考察了炉渣成分、温度、气相氧硫势对锰和铁在炉渣之间分布行为的影响。还发现（C2S-C3P）ss在水中的溶解行为与样品中C3P的比例和矿物相有关。根据这些结果，建立了炼钢渣硫化制锰的基本技术。
