George, silver's so cheap right now, that you'd have to go through a lot of
fixer to make recovery pay for itself.

However, there's the environmental angle to consider too. I extract silver
this way: I buy the finest-grade steel wool I can find, and, if it's not
sold as oil-free, I tear off maybe 1/4 of a pad, wash it in hot detergent,
stuff it in a funnel, and run my spent fixer through it a few times. What's
left, I dry, and eventually, will probably take to a local photo lab, to be
tossed in with their own reclaimed silver. Looks mostly like a blackish
sludge and steel wool. Alternately, you can probably take a couple of copper
sheets hook them up to a spare 12V battery, and directly extract metallic
silver onto the plates, but you will want some means of circulating the
fixer over them.
