Characterization of iron ore by visible and infrared ...

01/01/2015  The typically small sample area measured during Raman experiments, with spot measurements made in the range 2–5 μm in diameter, means that characterization of iron ore mineralogy can be facilitated at scales beyond that of most other conventional techniques, such as X-ray diffraction (XRD), and demonstrates the power of the technique for in situ, fine-scale identification and semiquantification of iron ore

Iron ore - Wikipedia

Metallic iron is virtually unknown on the surface of the Earth except as iron-nickel alloys from meteorites and very rare forms of deep mantle xenoliths.Some iron meteorites are thought to have originated from accreted bodies 1,000 km in diameter or larger. The origin of iron can be ultimately traced to formation through nuclear fusion in stars and most of the iron is thought to have ...
