  • In Line Leach Of Gold Solution Electrowinning

    201984 Electrowinning is defined as the cathodic deposition of metal in this example copper from a copper bearing solution by the passage of an electric current current using an insoluble anode. For copper the electrowinning reaction reaction is CuSO4 H2O ⇒ Cu ½O2 H2SO4 The overall reaction is the combination of two electrochemical half reactions.

  • Electrowinning - an overview ScienceDirect Topics

    An electrowinning cell of novel design has been described by Treasure (2000).Named as EMEW R cell, it consists of a cylindrical in place of planar electrodes. The outer tube is the cathode and the inner one is anode. The diameters of the electrode tubes are sized according to the particular application to minimize cell voltage for a given solution chemistry.

    ExperimentalResultsDiscussion of Results and ConclusionsThe current was supplied and controlled by a PAR 371′ potentiostat-galvanostat regulated by an EGG-PARC 175 universal programmer. Current and elapsed time were monitored using a Fluke 220B data logger. Total current was recorded by a Curtis 1002 integrator. Voltage waveforms were displayed on a Leader LBO-515 dual trace oscilloscope.All room temperature experiments used a 250-mL Pyrex beaker as the cell vessel. The solution was stirred with a magnetic stir bar and external stirring plate. On...
