If you put a carbon & stainless steel rod into the solution, & hook them up to a power source. the silver will come out of solution & stick to one of them (I can't remember which one is the cathode or anode). There used to be a local company that took spent mini lab/radiology lab chemicals & recovered the silver. They apparently also had a way of recovering the silver from old x-rays. I used to store my spent fixer in a plastic jerry can. When I had collected enough my Dad would take it to work and dump it in their dirty chemicals drum.
