%X The reduction rate of FeO in molten slags of two systems FeO-CaO-SiO_2-MgO and FeO-CaO-SiO_2 by solid carbon has been determined by the method of measuring the kinetic parameters in which a combination of the initial concentration in system with the weightless rate of reductant in the reaction process was made. The reduction rate determined by this study is of an apparent first order reaction of overall wt-% of FeO. The measured apparent activation energy is 222.60 kJ/mol. The empirical equation of the rate is v=-(W_s/A)dc/dt=1453.0exp(222600/RT)]·C Experimental results show that the convection diffusion is the rate-controlling step in the reduction of molten FeO by solid carbon.
