  • Pyrite: Mineral information, data and localities.

    Pyrite will slowly oxidize in a moist environment, and release sulfuric acid that is formed during the process. Well-crystallized specimens are generally relatively stable, while pyrite formed as sedimentary concretions has a tendency to decompose quickly.

  • How to Separate Gold from Pyrite

    In panning large samples, only one or two specks of gold could be seen, although the ore contained from 1 to 2 ounces per ton. This ore yielded only about 40 per cent, on being amalgamated, but over 90 per cent, was dissolved out by leaching the raw ore with cyanide of potassium, and similar results were obtained by chlorination.

  • Pyrite - Wikipedia

    Iron pyrite is unstable at Earth's surface: iron pyrite exposed to air and water decomposes into iron oxides and sulfate. This process is hastened by the action of Acidithiobacillus bacteria which oxidize the pyrite to produce ferrous iron and sulfate. These reactions occur more rapidly when the pyrite is in fine crystals and dust, which is the ...

  • Pyrite: The mineral pyrite information and pictures

    Pyrite was once used as a source of sulfur, but is now only a minor ore for both sulfur and iron. Pyrite from some localities is auriferous, and therefore is used as an ore of gold in gold-bearing localities.Pyrite was polished by the Native Americans in the early times and used as mirrors. Today, it is used as an ornamental stone, as well as a very popular stone for amateur collectors.
