2 Schwarz Global Consulting, Johannesburg, South Africa Corresponding author nilssgconsulting.co.za . Nodulation is a persistent problem in copper electrowinning, especially where high current densities are used. The resultant porous copper tends to contain impurity levels which are too high for LME quality.

Electrowinning is the process whereby metals, such as gold, are recovered from concentrated solutions by applying a voltage across electrodes immersed in the concentrated solution. The voltage applied across the electrodes cathode and anode results in a cathodic reaction which in turn results in the deposition of the metal from solution onto the cathode.The cathode is the electrode at which ...

Jan 07, 2014 Conventional copper electrowinning involves the decomposition of water at the anode and has a cell potential of approximately 2 V. If the anode reaction is changed to involve the oxidation of sulfur dioxide the cell voltage can be cut almost in half and this change can dramatically affect the overall energy consumption of a hydrometallurgical process. As well as saving energy, this reaction ...
