SILVER EXTRACTION FROM FIXED/HYPO
SOLUTION
I HAVE FIXED/HYPO SOLUTION CONTAINING SILVER. I NEED
INFORMATION REGARDING EXTRACTION OF SILVER BY ELECTROLYSIS
OF FIXED/HYPO SOLUTION.
THANKS FOR YOUR HELP.

Would you please answer this letter? Where I can find the
answer. Thanks for finishing.com.
Dear sir, at the beginning let me thank you for your
spirit of giving a hand of help to me.
I appreciate your assistance.
Here again I demonstrate my construction idea with the
diagram, so would you kindly identify the following points
1 - should the electrodes touch the bottom al
container.
2 - is there any specific graphite electrodes for this
construction? If yes identify length and diameter .
3 - Does both length and diameter effect on extraction?
4 - what is suitable position of electrodes? Vertical or
horizontal.
5 - How long is the distance between two electrodes?
6 - What is the type of current applied A.C or D.C
7 - What is the Applied Volts - Amperes - if I use
Rheostat.
8 - Dose the parameter i.e Volt-Amperes ŠŠ etc remain
unchanged if I use 5 liters of hypo instead of 30
liters.
9 - if I want electrolyte Agno3 solution what about
electrode are using - Ampere - Volt - Current ( D.C .AC )
your faithfully

Also I wanted to know how we can do this in small scale

I want to know all about silver extraction from
Hypo/Fixer & or photowaste. I am chemical engg. & do
the hobby research about the silver extraction from hypo or
photo waste.
Can somebody explain to me in detail about the construction
& calculation of the equipment to carry out this
process.
I have created small equipment with small transformer of
halogen lamp & carbon electrode; is it correct
approach?
please do send me detailed illustrated reply as soon as
possible.
Thanks,

We've never seen anyone provide a response of that great
a depth in 40,000 postings here, Santosh, so good luck but
don't hold your breath. But if you publish your detailed
plans here for your marginally successful system, maybe
someone will publish their suggestions for a better one. You
may want to keep your eye out for a copy of Kodak's 29-page
booklet "Recovering Silver from Photographic Materials"; as
of this writing there are copies available for $5 - $15 at
this link at Abe books . Good luck!
