  • University of Minnesota's Mineral Pages: Chalcopyrite

    Initially, it may be easy to confuse chalcopyrite, or copper pyrite (CuFeS2), with pyrite (FeS2), but the two can be distinguished by their relative hardness and chalcopyrite's iridescent tarnish. Copper is easily worked and relatively cheap so it is used for the bulk of the wiring that connects our society's electrical systems.
