The typical properties of the iron ore pellets are given in Tab 1. Process technology. There are four stages involved in the production of iron ore pellets. These stages consist of (i) raw material preparation, (ii) formation of green balls or pellets, (iii) induration of the pellets, and (iv) cooling, storage and transport of pellets.

Iron ore pellets are produced using a process called pelletizing. The raw material, iron ore fines or powders, is first blended to achieve the desired chemical composition. Then, it is ground into a fine powder and mixed with additives like limestone and bentonite. The mixture is pelletized by adding water and rolling it into small, rounded ...
