It's important to recover silver. Don't pour it down the drain! Wrong for many
reasons.Most of us don't use enough film/paper to make home silver recovery
practical- and the money possibly gained may not be worth the effort (and the
lovely aroma).If you have a photo lab in your home town, offer them your used
fixer; they'll be happy to take it. That's what I've done for quite some years.
The lab can use the few pennies and I can afford the loss.

Subject: [pure-silver] Re: Silver 'recovery'
A friend of mine who was a professional photographer had a machine that
electroplated the silver out. It had some thin metal disks (stainless steel, I
think) that the silver plated on in a tank full of spent fixer. He would then
remove the disks, flex them and the sheets of silver would pop off. I think he
recovered quite a bit of money doing that and selling the silver.

As much as I could into the carboy containing the used
Fixer… give it a good ‘shake now and again over the next
few days..you will soon find a precipitate on the bottom of
the carboy. After a week or so, I then syphon off as much
‘clear liquid as possible…without ‘disturbing’ the precipitate
Add more used fixer.. then not quite ‘dead’ developer, shake
and let the precipitate settle
After a few “rounds of the procedure I wash with ‘clean’ water
.. settle and rewash again a few more times…. After adding a last’wash
I shake and filter out the black precipitate which, according to
"what I was told provides’ I have a significant amount of what is known
as “Black Silver” probably the purest form of silver you can get
When ‘dry’ I take it to a friend who has a ‘muffle furnace’ where it
gets melted to provide a blob of silver on coming ‘out’ that is then
sold to a local ‘jewelry repair’ outlet for ‘cash’
MUCH BETTR than pouring it "down the drain”
