eric, you can remove the silver from used fixer with
copper... some folks use sheets of it
the silver & copper happily trade places, it's not really an
attack...
don't know about the other process you have in mind, though

Hello all,
Is is possible to use copper scraps to plate out silver from spent fixer?
There seems to be a mild attack on the copper if it is placed into spent fixer.
I am almost tempted to try copper plate etching for intaglio printing plates
using the fixer as a mordent.
I am have held off due to the potential of other by-products... my knowledge
of chemistry is really rusty.
Is there anyone on the list with chemistry hints, or a resource book that can
steer me in the right direction. I thank you in advance.
