    iron sulfide Schlumberger Oilfield Glossary

    A group of compounds containing iron in +2 (ferrous) and +3 (ferric) valence states and sulfur in 2 (sulfide) valence states. Examples are ferric sulfide [Fe 2 S 3], ferrous sulfide [FeS] and iron disulfide (FeS 2, which is found in the minerals marcasite and pyrite).Fe 2 S 3 and FeS 2 are insoluble, but FeS dissolves in alkaline muds to form a gelatinous solid, Fe(OH) 2, and soluble S2 ions.

    Acid Mine Drainage Ground Truth Trekking

    Summary. Acid mine drainage (AMD) refers to the outflow of acidic water from a mining site. In most cases, this acid comes primarily from oxidation of iron sulfide (FeS2, also known as pyrite or "fool's gold"), which is often found in conjunction with valuable metals. Acid mine drainage is a major problem with many hardrock mines, including almost all mines where the metal ore is bound up with ...
