Magnetite - Mindat

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 200-nm octahedral crystals of magnetite give some basalt surfaces an iridescent sheen (Nadin, 2007).

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. It is the most magnetic of all the naturally-occurring minerals on Earth. Naturally-magnetized pieces of magnetite, called lodestone, will attract small pieces

Hematite - Wikipedia

It is mined as the main ore of iron. Varieties include kidney ore, martite (pseudomorphs after magnetite), iron rose and specularite (specular hematite). While these forms vary, they all have a rust-red streak. Hematite is harder than pure iron, but much more brittle. Maghemite is a hematite- and magnetite-related oxide mineral.

Goethite - Wikipedia

Goethite is an iron oxyhydroxide containing ferric iron. It is the main component of rust and bog iron ore. Goethite's hardness ranges from 5.0 to 5.5 on the Mohs Scale, and its specific gravity varies from 3.3 to 4.3. The mineral forms prismatic needle-like crystals ("needle iron ore") but is

Pyrrhotite - Wikipedia

Pyrrhotite is an iron sulfide mineral with the formula Fe (1-x) S (x = 0 to 0.2). It is a nonstoichiometric variant of FeS, the mineral known as troilite.Pyrrhotite is also called magnetic pyrite, because the color is similar to pyrite and it is weakly magnetic.The magnetism decreases as the iron content increases, and troilite is non-magnetic.

Ulvöspinel - Wikipedia

Ulvöspinel was first described by Fredrik Mogensen (1904-1978) from a dolerite layered intrusion in the Ulvö Islands, Ångermanland, Sweden in 1943. The locality is an iron, titanium and vanadium mining area that has been active since the 17th century. It is common in titaniferous magnetite iron ore deposits.

tailing samples from the flotation and magnetic separation of iron ore. Qualitatively, the tailing samples revealed a mineralogy composed essentially by quartz, hematite, goethite and magnetite. Quantitatively, higher volumetric fractions in quartz and lower volumetric fractions in iron oxides/hydroxides and accessory minerals were verified on the flotation and coarse magnetic separation

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.
