Sample Proposal for an Iron Ore Pelletizing Plant
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.

Iron ore | BHP
Iron ores are rocks and minerals from which metallic iron can be extracted. There are four main types of iron ore deposit: massive hematite, which is the most commonly mined, magnetite, titanomagnetite, and pisolitic ironstone. These ores vary in colour from dark grey, through to deep purple, rusty red and bright yellow.
