Pyrite - Wikipedia

Iron pyrite is unstable when exposed to the oxidizing conditions prevailing at the Earth's surface: iron pyrite in contact with atmospheric oxygen and water, or damp, ultimately decomposes into iron oxyhydroxides (ferrihydrite, FeO(OH)) and sulfuric acid (H 2SO 4). This process is accelerated by the action of Acidithiobacillus bacteria which oxidize pyrite to first produce ferrous ions (Fe ), sulfate ions (SO 4), and release protons ( H , or H3O ). In a second step, the ferrous ions (Fe ) are oxidi
