This paper reports some experimental observations on reduction of FeO in molten slags by carbon saturated iron bath. A Tammann furnace was used to study the reaction. Kinetic results indicate a first order reaction with respect to FeO concentration. Results also indicate that the gas generated during the reduction reaction plays a significant role through stirring of the bath. A correlation established through the Morton number and the Reynolds number provides further insight into this phenomenon. Degree of reaction, defined using optical basicity values calculated on the basis of the overall composition of the slag provides results comparable to those obtained from the conventional values calculated on the basis of FeO concentration.
