Mining and processing: Iron ore is typically mined through open-pit or underground mining methods, depending on the depth and location of the deposit. After extraction, iron ore is processed to remove impurities and obtain the desired iron content through crushing, grinding, magnetic separation, and other beneficiation techniques.

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.
