The unit cell is twice as large, reflecting an alternation of Cu+ and Fe3+ ions replacing Zn2+ ions in adjacent cells. Chalcopyrite is an accessory mineral in Kambalda type komatiitic nickel ore deposits, formed from an immiscible sulfide liquid in sulfide-saturated ultramafic lavas. Chemical formula: CuFeS2. Chalcopyrite is a copper iron sulfide mineral that crystallizes in the tetragonal system. copper iron sulfide mineral. The name chalcopyrite comes from the Greek words chalkos, which means copper, and pyrites', which means striking fire. These rare elements are valuable and can berecovered as profitable by-pro… Dbl Clk - Start-Stop Rotation Minor amounts of elements such as Ag, Au, Cd, Co, Ni, Pb, Sn, and Zn can be measured (at part per million levels), likely substituting for Cu and Fe. Even though Chalcopyrite does not contain the most copper in its structure relative to other minerals, it is the most important copper ore since it can be found in many localities. Striated - Parallel lines on crystal surface or cleavage face. Because of its shiny look and often yellow color, it is sometimes mistaken for gold, and for this reason it is also called fool's gold.
