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.

Abstract: An electrolytic silver recovery apparatus for recovering metallic silver from silver-laden solutions wherein such apparatus has liquid-level controls, interval electrical power controls and removable electrodes is disclosed.

Abstract: An improved silver recovery system for automated X-ray film processors is disclosed. The fixer solution tank of an automated X-ray film processor is connected by overflow conduit and bottom discharge conduit to a surge-drip tank which is interconnected by a bottom orifice discharge and an overflow to a removable silver recovery unit. A high flow-rate pump interconnects the fixer solution tank with a fixer storage tank for rapid refilling upon complete discharge of the fixer from the fixer tank. Occasional emptying of the fixer tank is required for repairs and the like. More frequent emptying of the fixer tank is desired to enable more complete recovery of silver.
