    Copper electrowinning for copper refineries . Electrolytic copper refineries have an inherent need to control copper concentrations in the tankhouse.The process of electrorefining copper involves an impure copper anode and an inert cathode. An electric current is applied across the anode and cathode which causes the copper to dissolve from the anode to be then plated onto the cathode as pure

  • emew Blog

    Electrowinning is a very convenient and robust way to directly recover dissolved metals such as copper, silver, gold, nickel, cobalt, and tin from their aqueous states in a particular electrolyte. Not surprising then when talking about metal recovery that we tend to focus most of our attention on those metals that we are interested in with the

    However, electrowinning has proven to be an economical alternative, even more so when utilizing emew technology. Electrowinning can be used directly after the cyanide leach, resulting in fewer process steps, and therefore lower operating costs.

  • Leaching in Metallurgy and Metal Recovery emew Blog

    The Radomiro Tomic mine in Chile is a prime example of the success of copper heap leaching, followed by solvent extraction and electrowinning. Heap leaching technology is important to the future of metal recovery, since it can be applied to extract precious and base metals sitting in abandoned tailings, and/or waste management sites.
