Electrorefining of Copper - Universidade Federal do Rio
Electrorefining of Copper 1. Electrorefining – General Introduction In an electrorefining process, the anode is the impure metal and the impurities must be lost during the passage of the metal from the anode to the cathode during electrolysis, i.e. the electrode reactions are, at the anode: M → Mn+ + ne-and at the cathode: Mn+ + ne-→ M Electrorefining is a much more common process than

Electrowinning - an overview ScienceDirect Topics
Electrowinning has proved to be an effective and simple method for recovering gold from the eluate. Electrowinning is done simultaneously with the elution. The barren eluate is recycled to the eluant tank and is recycled for the next elution after the reagents have been made up to their relevant concentrations. Two operating plants, namely Penjom Gold Mine and Barbrook Gold Mine, have now

Electrowinning and Smelting - Resource Book
Electrowinning is performed in cells, constructed of non-conducting plastic material. The cell contains a set of cathodes (negative electrodes) and anodes (positive electrodes) immersed in the gold bearing eluate delivered from the elution circuit, or Sunrise Reactor. The eluate acts as a conductor between the cathodes and anodes. When the rectifier is switched on the electrowinning circuit is
