Iron - HyperPhysics Concepts

Iron pyrite, Fe 2 S, contains the iron, but it is difficult to isolate from the sulfur. This ore is used as a source for sulfur. A variation on pyrite is called pyrrhotite and the composition is written Fe 1-x S. Iron also forms the sulfide marcasite, FeS 2. Copper joins iron to form chalcopyrite, CuFeS 2.
