  • Electrowinning and Smelting - Resource Book

    Electrowinning and smelting are the final stages of gold production. The concentrated gold solutions produced in the elution circuit (pregnant eluate and by the Sunrise Reactor, are passed through the electrowinning cells which converts the gold ions (charged gold particles) in the solution into solid gold.

  • Electrowinning Gekko

    Electrowinning is the recovery of metals, such as gold and silver, from solution by passing a current through the solution. Electrons from the current chemically reduce the gold and/or silver ions, to form a solid metal compound on the cathode.

    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...
  • Electrowinning - an overview ScienceDirect Topics

    Electrowinning is the process of “winning” metal from solution using an applied voltage. Gold electrowinning is usually performed in relatively small vessels or cells that are about 1 m long and contain less than 1 m 3 of solution. These cells often contain several cathodes and anodes, although there is one extra anode.
