of chalcopyrite were optimized by varying the temperature (22, 60 and 90 °C), the concentration of FeCl 3 ( mol L −1) and the solidtoliquid ratio (30150 g L−1). The e ffect of di erent oxidizing agents was studied by mixing 50 mg of chalcopyrite with 1 mL of EG containing mol L−1 of oxidizing agent at 60 °C.

Oxidation of chalcopyrite in air ( atm of O2 equilibrated with atmospheric water vapour) results in a Fe(III)OOH surface layer on top of a Cu rich sulfide layer overlying the bulk chalcopyrite with the formation of Cu(II) and Fe(III) sulfate, and Cu(I)O on prolonged oxidation. Cu2O and Cu2Slike species have also been proposed to ...
Chalcopyrite Group. ChalcopyriteEskebornite Series. A major ore of copper. Common in sulfide veins and disseminated in igneous rocks. Weathering may lead to the formation of malachite, azurite, brochantite, langite and numerous other secondary copper minerals. A Znrich variety is known from Atlantis II Deep (see zincian chalcopyrite).Also, the MidAtlanticridge isocubanite may transform to ...
chalcopyrite, the most common copper mineral, a copper and iron sulfide, and a very important copper ore. It typically occurs in ore veins deposited at medium and high temperatures, as in Río Tinto, Spain; Ani, Japan; Butte, Mont.; and Joplin, Mo.

Chalcopyrite is a copper iron sulfide mineral that crystallizes in the tetragonal system. It has the chemical composition CuFeS2. It has a brassy to golden yellow color and a hardness of to 4 on the Mohs scale. Its streak is diagnostic as green tinged black. On exposure to air, chalcopyrite oxidises to a variety of oxides, hydroxides and ...
Chalcopyrite crystallises in the tetragonal space group I 2 d (122). This was first published by Pauling and Brockway in 1932 33 and has been confirmed by multiple authors. A detailed description of the structure determined on a natural chalcopyrite single crystal was published by Hall and Stewart in 1973 34 with lattice parameters a = (1) ...
Chalcopyrite is essentially unleached under the mild oxidizing conditions of heap leaching (very slow leach kinetics). It can, however, be leached under oxidizing conditions at elevated temperatures or by microbial leaching under lowpotential conditions (Gericke, Govender, Pinches, 2010).This has led to extensive study into leaching of chalcopyrite concentrates as an alternative to smelting.
