Uses for mineral Magnetite?

2011/11/13I would put iron steel manufacture as ONE use of magnetite. You should also note that since magnetite is a member of the spinel group of minerals {M2+,(M3+)2 O4} which are difficult to treat, magnetite is used but is not the preferred iron ore mineral. Haematite Get price

Magnetite in human tissues: A mechanism for the biological

104 Kirschvink et al. geologically produced magnetite. These characteristic features have enabled bac- terially precipitated magnetites to be identified in the fossil record in sediments up to 2 billion years old [Chang and Kirschvink, 19891.As shown in Figure 1, these same features are shared by the magnetite Get price

Magnetofossil

Magnetofossils are the fossil remains of magnetic particles produced by magnetotactic bacteria (magnetobacteria) and preserved in the geologic record. The oldest definitive magnetofossils formed of the mineral magnetite come from the Cretaceous chalk beds of southern England, while magnetofossil reports, not considered to be robust, extend on Earth to the 1.9-billion-year-old Gunflint Chert Get price

Iron ore

Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe3 O 4, 72.4% Fe), hematite (Fe Get price

Magnetite

Magnetite is not to be confused with Magnesite or Maghemite. Magnetite is a ferrimagnetic mineral with chemical formula Fe3O4, one of several iron oxides and a member of the spinel group. The chemical IUPAC name is iron(II,III) oxide and the common chemical name ferrous-ferric oxide. The formula for magnetite may also be written as FeOFe2O3, which is one part wstite (FeO) and one part Get price

Mineral Classics

Magnetite as a species is one of the most well known oxides in the mineral world, but despite its abudance around the world, fine specimens are still highly sought after by collectors. Places like the famous Binntal in Switzerland (the world's finest Magnetites have been found here) hardly produce specimens anymore, and top pieces are astronomically priced in today's market.

Brain Magnetite

Abstract - Although the mineral magnetite (Fe3O4) is precipitated biochemically by bacteria, protists, and a variety of animals, it has not been documented previously in human tissue. Using an ultrasensitive superconducting magnetometer in a clean-lab environment, we have detected the presence of ferromagnetic material in a variety of tissues from the human brain. Get price
