Pelletizing is the process through which iron ore fines are transformed into an agglomerated form called "iron ore pellets" suitable for use in an ironmaking furnace at a steel mill, such as a blast furnace or electric arc furnace. In its end product form, a typical iron ore pellet is roughly spherical in shape, measuring from 6 mm to 16 ...

The amount of these additives added are 5% of the mass of the iron ore. The mixture is mixed thoroughly inside a ball mill and transferred to a pelletizing machine. Once in the pelletizing machine, a level of moisture of approximately 9% is introduced by spraying water into the mixture. This will result in the formation of iron ore pellets.

Sample 3 is a high LOI (%) bearing iron ore pellet feed material, where % kaolinite and % goethite are present. As goethite is in fragile nature, the surface area is more after grinding in the ball mill for sample preparation. The moisture content in the green pellet increases with the increase of goethite due to its more surface area.
