Magnetite - Wikipedia

Magnetite is a rock mineral and one of the main iron ores, with the chemical formula Fe 3 O 4. It is one of the oxides of iron , and is ferrimagnetic ; it is attracted to a magnet and can be magnetized to become a permanent magnet itself.Magnetite Crystals (octahedrons) in Matrix, Bulk Iron Ore,,This natural iron ore specimen was mined in the USA Price: $14.95 This natural magnetite mineral specimen is a very solid piece composed of over 85% massive magnetite with some minor accesory minerals. The magnetite concentration in this natural iron ore specimen is high enough that a magnet will stick to its surface.Magnetite – natural iron oxide for several applications,Magnetite, or Fe 3 O 4, is a black ferri-magnetic natural iron oxide. This natural aggregate is a member of the spinel group. This natural aggregate is a member of the spinel group. LKAB Minerals' customers can be found all over the world and their use of Magnetite differs a lot.

Magnetite & Lodestone | Mineral Photos, Uses, Properties

Use of Magnetite as an Ore of Iron. 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.About ⋆ Universal Minerals, Inc.,Universal Minerals, Inc.
