The pelletizing of iron ore is a consolidation method to obtain a high-strength pellet. This method contains granulation of the mixed materials (such as iron ore, bentonite, and flux) in a pelletizing disc, drying of green pellet, firing of green pellet, and air cooling finally. The pelletizing process is summarized in Figure 4.
