ABSTRACT:
An electrolytic silver recovery apparatus for the recovery of metallic silver from silver-laden solutions is disclosed. The apparatus has liquid level controls, interval electrical power controls, and a removable cathode. The apparatus is used particularly in conjunction with x-ray film developing systems to recover silver values from spent fixer solution in a manner whereby at least a substantial portion of the fixer solution may be returned to the film processor's replenishing tank for reuse.
