    Copper Leaching Method

    At the Steptoe mill, in Nevada, a small leaching annex is treating oxidized copper ore in conjunction with flue dust at a cost of $0.08 per pound copper recovered. The actual cost of copper produced by leaching methods is, however, not of so much importance as the fact that ore may be handled in this manner which is not amenable to reduction by any other process.

    Sulphide Leaching

    Copper sulphate can be used to separate Copper from Nickel in a sulphide ore or Copper from Fe in Cu Fe sulphide ore. CuSO 4 solution can also be used for removing Pb, Zn, and Fe from copper sulphide ores. In presence of oxidizing agents: Ferric ion: Ferric sulphate or chloride react with metal sulphides liberating elemental sulphur, e.g.
