Electric arc furnace slags containing FeO-MgO-CaO-SiO2 reduced with carbon to identify the effect of FeO and CaO/SiO2. Lab scale reduction of FeO was done in an induction furnaceunder an Ar admosphere at 1773K. Molten pool of electrolytic iron was used to capture the reduced iron droplet from the FeO based slag by measuring the mass change of the iron pool. Degree of metallization of FeO was significantly affected by FeO concentration and CaO/SiO2. It was revealed that slag foaming and dispersed particles in the slag influenced the reduction phenomenon. Mass transfer coefficients of FeO in slag was calculated to understand and correlate the degree of metallization of FeO with the kinetics of the reaction.
