• Limonite Wikipedia

    Limonite (/ ˈ l aɪ m ə n aɪ t /) is an iron ore consisting of a mixture of hydrated iron(III) oxidehydroxides in varying composition. The generic formula is frequently written as FeO(OH)· n H 2 O, although this is not entirely accurate as the ratio of oxide to hydroxide can vary quite widely. Limonite is one of the three principal iron ores, the others being hematite and magnetite, and ...

  • Magnetic susceptibility of geologic materials

    The chart below shows the ranges of magnetic susceptibility and magnetite volume for common rock types. Note that the susceptibility scale is logarithmic, so there is a huge range of susceptibilities in geologic materials. Some relevant remarks are: Magnetite is, by far, the most magnetic mineral.

    For iron industry, there is a very strict sulfurcontent specification in magnetite concentrate, because pyrite is harmful mineral in iron ore. The observation under single polarizing microscope showed that the magnetite is closely combined with pyrite and pyrrhotine, and fine grain gangue mineral malcrystals are wrapped in the magnetite crystals.

  • Hematite | Geology Page

    Hematite is a mineral, colored black to steel or silvergray, brown to reddish brown, or red. It is mined as the main ore of iron. Varieties include kidney ore, martite (pseudomorphs after magnetite), iron rose and specularite (specular hematite). While the forms of hematite vary, they all have a rustred streak.

    Uses of Magnetite . 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

    Iron (Fe) is the most abundant element, but it only comprises approximately 6 percent of continental crust. Metallic iron is silverywhite, malleable, ductile, and may be readily magnetized. Elemental iron has a relatively high specific gravity () and high melting point. Iron is used primarily in the manufacture of iron and steel products.
