Chalcopyrite ( /ˌkælkəˈpaɪraɪt, -koʊ-/[6][7] KAL-ko-PY-ryt) is a copper iron sulfide mineral that crystallizes in the tetragonal system. It occurs in most sulfide mineral deposits throughout the world and has been the most important ore of copper for thousands of years. if (document.getElementsByTagName != null) The absence of xanthate on the mineral surface was confirmed by Fourier transform infrared spectroscopy. Selenium, Bi, Te, and As may substitute for sulfur in minor amounts. I - Data Info else In addition to sulfur (S), chalcopyrite contains some iron (Fe) and the proportions of these metals in the mineral are expressed by its chemical formula: CuFeS2. The name chalcopyrite comes from the Greek words chalkos, which means copper, and pyrites', which means striking fire. It often forms in association with Chrysocolla, with the Chrysocolla forming as an alteration around the Chalcocite.

The chemical formula (Zn, Fe) of sphalerite is S. It is azinc sulphide containing a variable amount of iron instead of zinc in themineral lattice. Drag2 - Resize Chalcopyrite in this environment is produced by concentration within a magmatic system. Associated copper minerals include the sulfides bornite (Cu5FeS4), chalcocite (Cu2S), covellite (CuS), digenite (Cu9S5); carbonates such as malachite and azurite, and rarely oxides such as cuprite (Cu2O). The chalcopyrite mineral with the chemical formula of CuFeS 2 is a “mixed redox-couple” cation-containing material, as defined here, where the “mixed redox couple” refers to two different metal cations with an opposite redox property bridged through a nonmetal atom, such as Cu(I)-S-Fe(III) within this crystal structure. Link to , From the Greek, chalkos, "copper" hence "Copper Pyrite. drag1 - LMB Manipulate Structure printWin.print(); Another difference is that the iron cation is not diamagnetic low spin Fe(II) as in pyrite. if (headTags.length > 0) Leaching Chalcopyrite is the holy grail for hydrometallurgists (Leachers), difficult to leach as the sulfur forms a layer over the mineral and makes the leaching slow. html += '\n\n\n'; Chalcopyrite is a brass-yellow mineral with a chemical composition of CuFeS2. Bornite is a copper iron sulfide mineral with a chemical composition of Cu5FeS4. Minable concentrations of bornite occur in hydrothermal veins, contact metamorphic zones, and in the enriched zone of many sulfide mineral deposits. Brass yellow, may have iridescent purplish tarnish. Chalcopyrite may also be found in coal seams associated with pyrite nodules, and as disseminations in carbonate sedimentary rocks. Pterostilbene, stilbenoid molecule. It occurs in igneous, metamorphic, and sedimentary rocks. Chalcopyrite is found in igneous rocks and copper-rich shales, and it is an important ore of copper. Pyrite: The chemical composition of pyrite is FeS 2. Scale: Picture size 0.11 mm. Pyrite has a black streak and gold has a yellow streak.[12]. Chemical Composition.
