What Are the Uses of Magnetite? (with picture)

Christian Petersen Magnetite is a source of iron ore which is commonly used in the production of steel. Magnetite is an iron oxide mineral belonging to the group known as spinels. It is a very common and is a valuable iron has been known to mankind since early history and led to the earliest discovery and understanding of magnetism....

ALEX STREKEISENMagnetite

Magnetite Fe 2+ Fe 2 3+ O 4 The spinel group minerals is represented by a dozen minerals with a generalized formula A 2+ B 2 3+ O 2 With a an essentially cubic closepacked oxygen arrangement with two different ion types in sixfold (octahedral) and fourfold (tetrahedral) coordination between the (111) closepacked layers. Three series are defined by the dominant trivalent ion: spinel ......

Is the magnetite mineral a nonsilie mineral?

 · It's composition can be Fe3 O4, or FeFe2 O4, depending if it's ferric or ferrous. There is no silicon in its composition, so it's a nonsilie, mafic mineralalso a diamond is the allotrope carbon ......

Magnetite, iron oxide, iron ore similarities and differences

 · LKAB mines magnetite, a natural iron ore, in its mines in Northern Sweden. Most of the iron ore is upgraded to highquality iron ore pellets and sold to steel production. However, through LKAB Minerals the group has established itself as the leading supplier of magnetite as an industrial mineral for various industries, where its properties add value in use for the customer....

What mineral group does magnetite belong to ...

 · Magnetite belongs to the spinel group of minerals. Sandstone, with a variety of mineralogies, does not belong to a mineral group....

Magnetite

Magnetite is a mineral and one of the main iron ores, with the chemical formula Fe 3 O 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. It is the most magnetic of all the naturally occurring minerals on Earth. Naturally magnetized pieces of magnetite, called lodestone, will attract small pieces of ......

Magnetite

 · Magnetite. Magnetite is a natural magnet! Part of a mineral group called the oxides, magnetite can usually be identified by its strong magnetism and dark color. Magnetite is often not very abundant, but it can be found in many different types of igneous, metamorphic, and sedimentary rocks. It can even be found in some meteorites....

Magnetite

The magnetite at Auen was found in one of these pegmatites in 1996. The actual pegmatite was severly altered, with a clay mineral, albite covered microcline and magnetite as main minerals. Small zircon, molybdenite sheets and a yellow, transparent mineral was present as accessory minerals. Most of the magnetite was partly altered to hematite...

Magnetite: Mineral information, data and localities.

Magnetite is an important, strongly magnetic 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)....

Magnetite Lodestone | Mineral Photos, Uses, Properties

 · Magnetite is very easy to identify. It is one of just a few minerals that are attracted to a common magnet. It is a black, opaque, submetallic to metallic mineral with a Mohs hardness between 5 and It is often found in the form of isometric crystals. It is the most strongly magnetic mineral ......
