Hematite vs Magnetite: Unveiling the Differences in Iron Ore

Hematite is mined from deposits around the world and can be easily extracted due to its abundance. Once extracted, hematite undergoes a process called beneficiation where impurities are removed and the iron content is increased. This results in high-grade iron ore that can be used in blast furnaces to produce steel.
