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.
