• This investigation devotes to the kinetics of the reduction of (MnO) with carbon-saturated liquid iron. The experiment condition involves high content realm of both (%MnO) and %Mn. It was found that the reduction is limited by the interfacial reaction. By means of a X-TV dynamic metallurgical phenomena displaying device, the slag-iron interface was proved to be the essential site for evolving the reduction product CO. The content variation of surface active agent S affects obviously on the reduction rate. If no carbon is added in slag, then a hump emerges on the curve of (%FeO) vs. reaction time. In this case, the apparent reaction order is 2. If there is a carbon addition in slag, the process is of apparent first order. Based on the three step model of reactions in series, the aforementioned phenomena and regularities were elucidated unitedly.
