Iron Ore | Geoscience Australia
The Brockman Iron Formation in this province is the most significant host for high-grade hematite iron ore deposits. Magnetite is an iron oxide mineral that is generally black and highly magnetic. The latter property aids in the beneficiation of magnetite ores.
The Assay Guide to Iron Ore
What is 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 …
