what are the uses of magnetite? reference mar 28, · what are the uses of magnetite? magnetite increases the density of most mixtures in which it is present. this property allows magnetite to be used in the manufacture of heavy concrete, water filtration, coal mining, landscaping and production of certain ironbased chemicals. when magnetite is added to a concrete mix, it produces heavy concretemagnetite sibelcomagnetite (iron oxide, chemical formula fe 3 o 4) is a dense, black powder which can be characterised by. high density; ferromagnetic properties; potential to heat up when subjected to microwave radiation (microwave induced heating).magnetite mindat mines, minerals and morethe magnetite at auen was found in one of these pegmatites in 96. 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 hematitea description of magnetite rocks and minerals 4 umagnetite. magnetite is strongly magnetic. it was used by the ancient chinese to make the first magnetic compasses. the chemical formula is fe 3 o 4, commonly called ferrousferric oxide, and is valuable as an iron ore. magnetite reacts with oxygen to produce hematite, another iron ore. in crystalline form magnetite is usually octahedral.magnetite sibelco10. 65. portafer m is the brand name for sibelcos magnetite. benefits due to its ferromagnetic properties, using portafer m63 it is possible to develop plastic magnetic articles. microwave induced heating microwave radiation enables rapid processes and curing of sealants and adhesives, even of bond lines that are thick or difficult to access.magnetite new world encyclopediamagnetite is a ferromagnetic mineral with the chemical formula fe 3 o 4 and the common chemical name ferrousferric oxide, which indicates the mineral comprises both a ferrous component, feo (wüstite), and a ferric component, fe 2 o 3 (hematite). magnetite is one of several types of iron oxide and its official (iupac) name is iron(ii,iii) oxide. it is a member of the spinel group of mineralsmagnetite mineral dataname origin named for magnes, a geek shepherd, who discovered the mineral on mt, ida, he noted that the nails of his shoe and the iron ferrule of his staff clung to a rock.
magnetite geology wiki fandommagnetite is a rock mineral and one of the main iron ores, with the chemical formula fe3o4. 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.56 it is the most magnetic of all the naturallyoccurring minerals on earth.57 naturallymagnetized pieces of magnetite, called lodestone, will attract smallgemstone information magnetite meaning and propertiesmagnetite is a rock mineral and, along with hematite, is mined as one of the main iron ores. scientists have discovered evidence that magnetite exists in the human brain and have theorized its presence can affect longterm memory. magnetite power was used by the germans in the 30s to develop magnetic acetate tape for audio recording.chemical composition fe 3 o 4magnetite mineral britannicamagnetite, 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 (q.v.) group.minerals 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.magnetite meanings, properties and powers the completeapr 23, · magnetite is very easy to recognize because its one of the very few gemstones that get attracted to a common magnet. its the most magnetic mineral that can be found, hence the name. its also known as lodestone or magnetic hematite. its blackgrey in color, but there are also magnetite stones that are grey and silver grey.estimated reading time 9 minsmagnetite mineral facts information pagemar 30, · magnetite mineral information page at mineralminers your online link for factual scientific mineralogical magnetite information about the natural iron ore known as magnetite and also lodestone, with links to natural magnetite specimens and magnetite samples as well information on magnetite mining locations and background info on magnetite physical properties, occurance, magnetitemagnetite jewelry etsymen's magnetic magnetite lodestone single bracelet, magnetite gen iron pyrite disk single bracelet, magnetite jewelry, magnetic jewelry lodestone magnetite 100% genuine spiritual healing crystal mineral stone rst807 *certificated* ukge 5 out of 5 stars (3,557) .01magnetite lodestone mineral photos, uses, propertiessignificancepropertiesgeologyuseproductionother usesformationscopemagnetite is a very common iron oxide (fe3o4) mineral that is found in igneous, metamorphic, and sedimentary rocks. it is the most commonly mined ore of iron. it is also the mineral with the highest iron content (72.4%).see more on geology chemical classification oxide
