Electrorefining - an overview ScienceDirect Topics

It is necessary to periodically remove some of the impure electrolyte and to top it up with clean electrolyte containing high concentrations of dissolved silver. The silver in the spent electrolyte is recovered and returned to the refining circuit, which, together with incompletely dissolved anodes, leads to a sometimes significant recycling loop within the electrorefining process.
