The Assay Guide to Iron Ore
Iron ore is a mineral substance that generates metallic iron (Fe) when heated with a reductant. Iron ore generally comprises iron oxides, the primary forms of which are magnetite (Fe3O4) and hematite (Fe2O3). Hematite is widely considered one of the most important iron ores due to its high-grade concentrate of iron and its abundance.
