    In sedimentary rocks pyrite is usually found as a replacement mineral, when the iron and sulphur that is present in the sediments chemically combine to replace the original chemical composition of organic matter that is in the process of becoming fossilised.

  • How Pyrite Is Mined And Processed

    Iron pyrite is a fairly common mineral, and is mined or extracted globally for its many industrial uses, such as extraction of the sulphur for sulphur dioxide or sulphuric acid, and also as an ore for iron. It oxidises readily, making it easy to extract the component minerals, but care must be taken as this also makes it quite combustible.

  • Pyrite Wikipedia

    Iron pyrite is unstable at Earth's surface: iron pyrite exposed to atmospheric oxygen and water decomposes into iron oxides and sulfate. This process is accelerated by the action of Acidithiobacillus bacteria which oxidize pyrite to produce ferrous iron, sulfate, and protons (H+

  • Pyrite Mineral Uses and Properties

    Other usesCharacteristicsPropertiesAppearanceCompositionIndustryUsesEffectsSafetyFormationThe conditions of pyrite formation in the sedimentary environment include a supply of iron, a supply of sulfur, and an oxygen-poor environment. This often occurs in association with decaying organic materials. Organic decay consumes oxygen and releases sulfur. For this reason, pyrite commonly and preferentially occurs in dark-colored organic-rich sediments such as coal and black shale. The pyrite often replaces organic materials such as plant debris and shells to create interesting fossils composed of pyrite.
