MAGNETITE (Iron Oxide) - Amethyst Galleries: Magnetite

Magnetite is an oxide of iron (as is hematite).It is not a component of ordinary rust, although it can form as iron oxidizes in a dry environment. When you see sparks from welding operations or from iron striking a hard surface (as when it is held against a spinning grinder), the sparks are due to the rapid (and exothermic) oxidation of tiny particles of iron into magnetite.

Magnetite: Mineral information, data and localities.

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

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.

Iron ore - Wikipedia

Increasing iron ore demand, coupled with the depletion of high-grade hematite ores in the United States, after World War II led to development of lower-grade iron ore sources, principally the utilization of magnetite and taconite. Iron-ore mining methods vary by the type of ore being mined.

Magnetite - Wikipedia

Huntington patients have not shown increased magnetite levels; however, high levels have been found in study mice. Applications. Due to its high iron content, magnetite has long been a major iron ore. It is reduced in blast furnaces to pig iron or sponge iron for conversion to steel. Magnetic recording

University of Minnesota's Mineral Pages: Hematite

Other minerals, such as magnetite, contain higher concentrations of iron, but hematite is so much more abundant that it is the most economically important iron ore. In North America, over 90% of our iron comes from hematite deposits and without hematite our steel-based society could not exist.

Magnetite -

Magnetite (Fe 3 O 4) is a common iron oxide mineral.It is a member of the spinel group. These are minerals that share the same structure but differ in chemical composition. Other notable members of the group are chromite and spinel.Magnetite is among the two major sources of iron.
