Electrowinning - 911 Metallurgist
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 ...

This gold electrowinning cell was designed and manufactured by SX Kinetics for a customer in Spain. This EW cell with 9 cathodes and 10 anodes is sized to produce up to 100 kg of gold per week. Copper or Cobalt Electrowinning Pilot Plant: 0.5 kg per day
Alternate Anode Reaction for Copper Electrowinning
the excess sulfuric acid and development of anode materials and electrolyte flow manifold design. The research project included a large pilot-plant scale process demonstration at a commercial electrowinning plant. The energy required to produce copper using the FFS process instead of present electrowinning
Solvent Extraction & Electrowinning (SX/EW) Plant Design
The electrode spacing in the cells was set at 101.6 mm with 46 cathodes and 47 anodes. The starter sheet blanks were of stainless steel design 316L and harvested daily to produce 1.0-meter by 1.0-meter size sheets. The commercial section cells operating design was for 182 A/m 2 with a seven-day plating cycle.

Elution and electrowinning of gold from gold-selective strong ...
Under these conditions the rate of gold recovery is controlled by the rate of electrowinning in the cell; in other words the elution process would have been completed in a shorter time had a larger electrowinning cell been used. An alternative design would be to use the same total cathode area but in a long narrow cell with a lower flow rate.
