Magnetite: Mineral information, data and localities.

JacobsiteMagnetite Series. MagnesioferriteMagnetite Series. Magnetite is an important iron ore, along with hematite. Nanoinclusions of magnetite crystals cause the iridescence of Rainbow obsidian (Nadin, 2007). Extremely thin layers of 200nm octahedral crystals of magnetite give some basalt surfaces an iridescent sheen (Nadin, 2007)....

What Are the Uses of Magnetite? |

Full Answer. It is also used in coal mining operations as a slurry with water to remove the heavier impurities by allowing the less dense coal to float to the surface. The magnetite can be reused in this process 90 percent of the time. Magnetite is also used as a source of iron to manufacture ironbased chemicals and fertilizers....

Jul 13, 2012· Banded ironformation in the Precambrian of Ontario, Canada. This is an exposure of glacially eroded, Archeanaged, folded, magnetiterich banded iron formation (BIF). An adjacent roadcut shows these BIFs perched atop basement rocks. Occasional patches of shiny glacial polish are present. I'm not absolutely sure about the formal stratigraphic name of this unit at this site, but it ....

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....

Magnetic Properties: Mineral Properties The Mineral and ...

Magnetic properties of minerals are defined as follows: Ferromagnetism describes strong attraction to magnetic fields. This property is exhibited in few minerals, notably Magnetite and Pyrrhotite. Paramagnetism is weak attraction to magnetic fields. The attraction is usually discernible, but it may be so weak that it is undetectable....
