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.
