Abstract

This work deals with kinetic description of carbothermic reduction of iron oxides using microwaves as power source. Previous researches shown that it is possible to conduct this kind of processes successfully, but real kinetic comparisons between conventional and microwaves procedure have been presented partially. The aim of this work is to describe reduction kinetics, taking into account how the iron oxide is reduced by microwaves compared with conventional energy supply. In this study we used iron ore in pellet shape and dust. We found that both, pellet and dust reduction stops when it reaches approximately 40%, even at whole power
