    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 Mineral Uses and Properties

    Other usesCharacteristicsPropertiesAppearanceCompositionIndustryUsesEffectsSafetyFormationThe name \"pyrite\" is after the Greek \"pyr\" meaning \"fire.\" This name was given because pyrite can be used to create the sparks needed for starting a fire if it is struck against metal or another hard material. Pieces of pyrite have also been used as a spark-producing material in flintlock firearms.

    Pyrite problems in the coal mining industry.

    The presence of pyrite (FeS2) in coal can cause or contribute to several problems for the coal mining industry. These problems, which include spontaneous combustion, roof falls, floor heave, and accidental explosions in coal surface mining when ammonium nitrate-fuel oil (ANFO) explosives are used, result from pyrite oxidation.
