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 presence of other valuable minerals, such as chalcopyrite and gold. In the ...
