In this study, the kinetics of reduction of Attepe iron ore by H-2 in a batch fluidized bed is analyzed at temperatures of 873 K, 973 K, and 1073 K (600 A degrees C, 700 A degrees C, and 800 A degrees C). It is determined that the reduction route includes two consecutive regions controlled by distinct steps. The first region which takes place at low reduction levels is determined to be controlled by nucleation of wustite, while the following is determined to be controlled by gas/solid reaction occurring at metallic iron/wustite interface. An ad-hoc model is used to represent the reduction of Attepe iron ore to metallic iron with good accuracy.
