  • Estimation of Fe in Magnetite Minalyze

    Significant portions of the total Fe in a magnetite deposit can be hosted in hematite or pyrrhotite, and of course silicate minerals. A Swedish iron oxide-apatite deposit, explored by Nordic Iron Ore, contains both magnetite and hematite. Drill cores from this project were analysed with Minalyzer CS. Magnetite content has been measured with a Satmagan. Some samples display higher Fe

  • Iron(II,III) oxide Wikipedia

    Iron(II,III) oxide is the chemical compound with formula Fe 3 O 4.It occurs in nature as the mineral magnetite.It is one of a number of iron oxides, the others being iron(II) oxide (FeO), which is rare, and iron(III) oxide (Fe 2 O 3) also known as hematite.It contains both Fe 2+ and Fe 3+ ions and is sometimes formulated as FeO ∙ Fe 2 O 3.This iron oxide is encountered in the laboratory as a

  • Magnetite (Fe3O4): Properties, Synthesis, and Applications

    Magnetite’s Curie temperature is observed at 850 K. Below the Curie temperature, magnetic moments on tetrahedral sites, occupied by ferric species, are ferro-magnetically aligned while magnetic moments on octahedral sites, occupied by ferrous and ferric species, are antiferro-magnetic and cancel each other; such combined behavior is termed ferrimagnetic (Cornell and Schwertmann, 1996

    18/10/2020· Iron oxides are chemical compounds which have different polymorphic forms, including γ-Fe2O3 (maghemite), Fe3O4 (magnetite), and FeO (wustite). Among them, the most studied are γ-Fe2O3 and Fe3O4, as they possess extraordinary properties at the nanoscale (such as super paramagnetism, high specific surface area, biocompatible etc.), because at this size scale, the quantum effects affect

  • Local structure of magnetite and maghemite and chemical

    ideal values of 72.34 wt% and 69.94 wt%, respectively. Because the difference between them is 2.4, it is possible to determine the Fe 2 O 3 and FeO ratio by assuming that the total weight percentage of cation and oxygen should be 100%. The percentage of Fe 2 O 3 and FeO for each natural specimen was re-calculated so that the total weight might

  • Controlling exchange bias in Fe3O4/FeO composite

    The magnetite nanoparticles were prepared by conventional co-precipitation from FeCl 2 and FeCl 3 at high values of pH. Iron salts were dissolved in water with a magnetic stirrer for 1 h. The pH value was increased by adding NaOH. The colour of the solution turned to black immediately, inducting magnetite formation. Magnetite particles were removed from the solution by using permanent magnet

  • Magnetite an overview ScienceDirect Topics

    Usually, the magnetite-rich compositions are ferrimagnetic at ambient temperatures (i.e., T C > 273 K) with high saturation magnetization values but never larger than that of pure magnetite (Table 2). Although spinels are common in mafic and ultramafic rocks, Fe-rich spinels other than titanomagnetite almost never dominate the remanence. An exception may be in certain archaeological copper

  • 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).
