  • 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.

This causes gold to collect on

  • 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.
