What does copper pyrites mean? definition, meaning and ...

For the Rokana slag, the and cobalt recoveries were 88.5% and 43.6%, respectively. The results of this study have shown that the roasting of slags with , followed by water leaching of the calcines obtained, is a good method for recovery, but only a proportion of the cobalt, nickel and zinc is extracted

  • Australian miners eye cobalt/copper from pyrite

    Oz Minerals, one of Australia's biggest producers, has entered into a testwork cooperation agreement with Cobalt Blue to confirm whether cobalt, and gold can be recovered from

  • Why is the extraction of copper from pyrites more

    On the other hand, the Gibbs free energy of formation of Cu 2 O is greater than that of CO. Hence, C can reduce Cu 2 O to Cu. C s +Cu 2 O s → 2Cu s + CO g Hence, the extraction of copper from its pyrite ore is difficult than from its oxide ore through reduction


    Large amount of copper are obtained from copper pyrite CuFeS2 by smelting. Ores containing 4% or more copper are treated by smelting process. Very poor ores are treated by hydro-metallurgical process. For latest information , free computer courses and high impact notes visit :

  • Extraction of Copper and Zinc | Chemistry, Class 12

     · iii is converted to ferrous sulphide FeS, cuprous sulphideCu 2 S which are partially oxidised. 2CuFeS 2 + O 2 —–> Cu 2 S + 2FeS + SO 2. . 2FeS + 3O 2 → 2FeO + 2SO 2. 2CuS + 3O 2 → 2Cu 2 O + 2SO 2. 3 Smelting. The roasted ore is mixed with some powdered coke and sand and is heated strongly in a blast

  • Copper-pyrites - Encyclopedia

    COPPER-PYRITES, or Chalcopyrite, a CuFeS2, The name copper-pyrites is from the Ger. Kupferkies, which was used as far back as 1546 by G. Agricola chalcopyrite from XaXK6s, " copper," and pyrites was proposed by J. F. Henckel in his Pyritologia, oder Kiess-Historie 1725

  • The Extraction of Copper - Chemistry LibreTexts

     · The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as C u F e S 2 are converted to copper by a different method from silicate, carbonate or sulfate . also known as copper pyrites and similar sulfide are the commonest of copper

  • The interaction between copper species and pyrite surfaces

     · The activation process on surfaces has been considered to be an electrochemical process involving the adsorption of Cu 2 + onto surfaces and the reduction of CuII to CuI with simultaneous oxidation of resulting in the formation of a CuI-sulfide phase Weisener and Gerson, 2000a, Weisener and Gerson, 2000b

  • Copper extraction

    ores containing chalcopyrite can be concentrated to produce a concentrate with between 20% and 30% -in-concentrate usually 27–29% the remainder of the concentrate is iron and sulfur in the chalcopyrite, and unwanted impurities such as silicate gangue minerals or other sulfide minerals, typically minor amounts of
