  • Gold Metallurgy Leaching in Cyanicides

    Leaching gold in Calcine. The principal cyanides in the calcine are copper, ferrous iron, and smaller amounts of Mo, Co, Ni, Mn, etc. Most of the cyanicides can be removed by water washing, but this step cannot be used owing to the loss of about $0.70 in gold resulting from the use of salt in the roast.

  • Influence of Ferric and Ferrous Iron on Chemical and

    The driving force in the leaching of metallic sulfides such as chalcopyrite, chalcocite and covellite is deter mined by the difference in the rest potential of the min erals present, and the redox potential of the leaching so lution which mainly depends on the ferric to ferrous iron ratio as described by the Nernst equation (Equation (1)) [1].
