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.

Dry processing of iron ore: In dry processing of iron ore, ROM is generally crushed below 40 mm through three-stage crushing and thus segregated by screening into 10–40 and −10 mm fractions. For softer ore, tumbler index is generally low and hence lump ore is crushed below 10 mm to produce fine product. Yield from the plants has …

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.
