electrolytic cell use for silver recovery

Electrolytic Silver Recovery - Industrial Wastes

2021-8-11  Electrolysis, or more specifically electrowinning, is the most widely used and universally applicable method for silver recovery in the photoprocessing industry. An electrolytic silverrecovery cell consists of a cathode and an anode. Oxidation occurs at the anode (positive electrode) and reduction at the cathode (negative electrode).
