Iron ore is a naturally occurring mineral from which iron is extracted. It is primarily composed of iron oxides, including hematite (Fe2O3) and magnetite (Fe3O4). Iron ore is a key raw material used in the production of steel, which is essential for various industries like construction, transportation, and manufacturing. The ore is typically mined from the Earth’s crust, processed to remove impurities, and then refined to produce high-purity iron or steel. It comes in different grades, with higher-grade ores containing a higher percentage of iron content.
