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

  • METALLURGY OF COPPER-EXTRACTION OF COPPER-BLISTER

    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 : www.citycollegiate.com
