Silver Recovery Systems, Electrolytic Plating Cell
Definition : Equipment designed to recover silver from solutions using an electrolytic process consisting of electroplating silver onto a plating cell. The electrolytic plating cell acts as the cathode in the electrolytic process; the process may be performed in a fixing tank or in a separate tank to facilitate collection of the used fixer. Silver is removed from the fixing solution when a controlled, direct electric current passes between the electrodes, causing the silver to plate onto the cathode in a form that is 90 to 96 percent pure; the plated cathodes are periodically removed and the plated silver is stripped off for later use. Electrolytic plating cell systems are used mainly in healthcare facilities to recover silver from solutions used during radiographic film processing.
