  • 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.

  • Pyrite (Iron Sulfide) Ohio History Central

    Pyrite is very common in the earth's crust. It has been used as an ore for sulfur, and sometimes as a source of iron. The more easily mined hematite, however, is a preferred source of iron. During the Second World War when North American sources of native sulfur were being used up, pyrite was mined for its sulfur content.
