iron ore processing from pyrite

  • 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 form it takes in most mining operations.
