University of Minnesota's Mineral Pages: Pyrite

Despite being a common, iron-rich mineral, pyrite is rarely mined for its own sake, and most of our iron is produced from magnetite and hematite deposits. Those iron oxide minerals occur in larger concentrations and volumes than pyrite, so they are a more economical iron source. Vein pyrite, however, may reveal the.

Sphalerite with Pyrite and Galena (#90) | Geology Department .

Sphalerite (ZnS), pyrite (FeS2), and galena (PbS) have at least one thing in common: they are all metal sulfides. Many ore minerals (that is, minerals that contain elements of such value that they are mined as "ores" to obtain those elements) are sulfides. The desired elements may be found in other minerals, but perhaps.
