    Pyrite enjoyed brief popularity in the 16th and 17th centuries as a source of ignition in early firearms, most notably the wheellock, where a sample of pyrite was placed against a circular file to strike the sparks needed to fire the gun. Pyrite has been used since classical times to manufacture copperas (iron(II) sulfate). Iron pyrite was heaped up and allowed to weather (an example of an early form of heap leaching). The acidic runoff fro

    Pyrrhotite is an iron sulfide mineral with the formula Fe(1-x)S (x = 0 to 0.2). It is a nonstoichiometric variant of FeS, the mineral known as troilite. Pyrrhotite is also called magnetic pyrite, because the color is similar to pyrite and it is weakly magnetic. The magnetism decreases as the iron content increases, and troilite is non-magnetic.

    1. Introduction. Iron pyrite (FeS 2) has a suitable band gap of 0.95 eV and a very high absorption coefficient (≥5 × 10 5 cm −1 for λ ≤ 700 nm) which is two orders of magnitude greater than that of crystalline silicon [].Such a high optical absorption coefficient would allow absorption of 90 % of incident light by a pyrite film as thin as ~40 nm (neglecting light scattering).

    And if you’re thinking that Iron Pyrites is magnetic then, yes it is, but only slightly. It depends largely on the iron ore content of the Pyrite but it will be weak in magnetic strength so it’s unlikely to ‘stick’ to a magnet. Pyrite tends to be abundant within geothermal mineral deposits and among coal beds.

    Hematite and magnetite are two iron oxide minerals. Most iron ore deposits consist mainly of hematite, magnetite, or both. Iron oxide concretions, iron oxide nodules, and ironstones are often mistaken for meteorites because their unusual shapes catch people’s attention and they are denser than most other rocks. Hematite concretions form by precipitation of iron oxide from iron rich solutions.

    Pyrite is a constant FeS2 (one atom of iron and 2 atoms of sulfur). Pyrrhotite’s chemical composition is: Fe(1-x)S (x=0-0.17) Please don’t ask me to expound on that. Pyrrhotite is sometimes referred to as magnetic pyrite because the color is similar to pyrite and it has some magnetic properties.

  • Iron

    Iron (Fe) is the most abundant element, but it only comprises approximately 6 percent of continental crust. Metallic iron is silvery-white, malleable, ductile, and may be readily magnetized. Elemental iron has a relatively high specific gravity (7.87) and high melting point. Iron is used primarily in the manufacture of iron and steel products.
