In general, pelletization of iron ore is a process where the feed is a mixture of highgrade hematite/magnetite ore mixed with binder and coke breeze as additives to form pellets for the production of iron and steel [5]. Such types of initiatives can eradicate the crises of highgrade iron ore demand as pellet feed material as well as support ...

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.
