Frequently Asked Questions | The Magnetite Network

What is the difference between magnetite and hematite iron ore? How does this affect greenhouse gas emissions? Hematite, or Direct Shipping Ore, has a different chemical make-up (Fe2O3) than Magnetite (Fe3O4). Magnetite contains less iron than hematite and is, therefore, of little value in its raw state. In order for.

Scanning electron microscopy systems also can misidentify minerals with close chemical composition, i.e. hematite as magnetite and vitreous goethite as hematite. In OIA, iron minerals with slight differences in their oxidation or hydration state are more easily and directly recognisable by correlation with their reflectivity.

Magnetite & Lodestone | Mineral Photos, Uses, Properties

Most of the iron ore mined today is a banded sedimentary rock known as taconite that contains a mixture of magnetite, hematite, and chert. Once considered a waste material, taconite became an important ore after higher grade deposits were depleted. Today's commercial taconites contain 25 to 30% iron by weight.
