Iron Minerals

Pure iron element is found in the Eather's core and in the outer space (meteorites), but in the crust of the Earth iron is found in alloys or minerals.



The main iron minerals are iron oxides magnetite, hematite, limonite and goethite.

The most important iron ore is hematite.

 

Other minerals that contain iron include aegirine, aerinite, 
allanite, alloclasite, alluaudite, amarantite, anapaite, andradite, ankerite, annite, anthophyllite, antitaenite, arsenopyrite, arthurite, astrophyllite, augite, axinite, bagrationite, balangeroite, beraunite, berthierite, beudantite, biotite, bonaccordite, bornite, briartite, bronzite, bukovite, calderite, carminite, celadonite, cerite, chaidamuite, chalcopyrite, chamosite, chapmanite, childrenite, chlorastrolite, chondrodite, chromite, cleusonite, clinohumite, cobaltite, coconinoite, cohenite, collinsite, columbite, copiapite, cordierite, corkite, coyoteite, cronstedtite, crossite, cubanite, cummingtonite, cylindrite, cyrilovite, demantoid, emmonsite, enstatite, epidote, ericssonite, eudialyte, fayalite, ferberite, ferrihydrite, ferrimolybdite, ferroselite, fluororichterite, fougerite, franklinite, freibergite, fukuchilite, gadolinite, galaxite, germanite, glaucodot, glauconite, glaucophane, gormanite, graftonite, greigite, grunerite, halotrichite, hapkeite, haxonite, hedenbergite, hercynite, hisingerite, homilite, hornblende, humite, hypersthene, ilmenite, ilvaite, indite, jacobsite, jamesonite, jarosite, jeffersonite, kamacite, kamiokite, kankite, keilite, kesterite, knebelite, kremersite, lazulite, lepidocrocite, lipscombite, lodestone, ludwigite, lulzacite, maghemite, magnesioferrite, marcasite, melanterite, melilite, messelite, mohrite, mooihoekite, niningerite, olivine, omphacite, oregonite, osumilite, ottrelite, pentlandite, phlogopite, pigeonite, povondraite, purpurite, pyrite, pyrrhotite, rhodonite, riebeckite, ringwoodite, roaldite, sabieite, safflorite, saponite, scorodite, scorzalite, segelerite, sekaninaite, sewardite, siderite, siderotil, smaltite, stannite, staurolite, sugilite, switzerite, taconite, taenite, talnakhite and tapiolite.
