magnetic properties of iron ore

Magnetite mineral
Magnetite, also called lodestone, or magnetic iron ore, iron oxide mineral (FeFe 2 O 4, or Fe 3 O 4) that is the chief member of one of the series of the spinel () in this series form black to brownish, metallic, moderately hard octahedrons and masses in igneous and metamorphic rocks and in granite pegmatites, stony meteorites, and hightemperature sulfide veins.

Iron processing
Iron (Fe) is a relatively dense metal with a silvery white appearance and distinctive magnetic properties. It constitutes 5 percent by weight of the Earth''s crust, and it is the fourth most abundant element after oxygen, silicon, and melts at a temperature of 1,538° C (2,800° F). Iron is allotropic—that is, it exists in different forms.

University of Minnesota''s Mineral Pages: Calcite
If a mafic magma cools slowly enough, dense magnetite crystals may settle as they crystallize, to form large magnetite ore bodies with a strong magnetic character. Magnetite can also form during contact metamorphism of impure ironrich limestone, and in high temperature hydrothermal sulfide vein deposits.

Difference Between Magnetite and Hematite
Jan 28, 2012· Magnetite is an iron oxide with the chemical formula Fe 3 O 4 whereas hematite is an iron oxide with the chemical formula Fe 2 O 3. Magnetite iron is in +2 and +3 oxidation states whereas, in hematite, it is only in +3 oxidation state. This is the key difference between magnetite and hematite.

Properties of Iron
Bog iron ore is limonite or goethite, deposited with the aid of iron bacteria in anaerobic swamps. The iron is carried in by waters containing CO 2 as soluble bicarbonates. The organic matter reduces it to oxides, which make characteristic iridescent patches on the water, then precipitate on the bottom of the marsh to form an ironrich layer.
