The pelletizing process, where the crude ore from the mine is upgraded, involves several steps, including grinding, balling, and induration; see Figure 1 to the left. In the gratekiln induration process []—see Figure 1 to the right—the sintering is mainly taking place in a rotary kiln, where the pellets increase their strength and metallurgical properties.
