Letter 10011 I HAVE FIXED/HYPO SOLUTION CONTAINING SILVER. I NEED INFORMATION REGARDING EXTRACTION OF SILVER BY ELECTROLYSIS OF FIXED/HYPO SOLUTION. THANKS FOR YOUR HELP. MAROUKY R
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  |
|
|
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

++++++ We very rarely see anyone provide a response of that great a depth in this forum, Santosh; calculations & illustrations invariably require paying a consultant. But if you publish your detailed plans here for your system, maybe someone like Maroky will respond with suggestions for improvements. You may want to keep your eye out for a copy of Kodak's 29-page booklet Recovering Silver from Photographic Materials. Best of luck with your efforts!

Dear sir
I am a radiographer working in one of the teaching hospital in Ghana
and would know step by step method of constructing a silver
extraction machine and also the method of extracting it, for i am a
very good designer. We have a lot of this film and fixer solution
which we have just been washing into the drain.May i know if i can
set of a small company to extract this silver from this expired x-ray
films and the waste fixer solutions very profitably?
Can i get a pure 100% silver?
thank you

Hi, Jamel. Letter 15559 has over a hundred entries on this same topic and we have other threads on the same topic as well.
It seems that the overwhelming majority of the people who post here are dissatisfied with their recovery results: they are getting less silver, making less money, and working harder than they expected. My own explanation for such widespread disappointment is certainly not that all of these hundreds of people are too dumb to figure the operating parameters out -- but that someone out there is promising people more silver, more money, and less work than is realistic. That is to say, while the technology of silver recovery from photographic waste is real, the promise of riches may be greatly exaggerated.

I would urge that people look in a library or spend a few dollars for the above-referenced booklet from Kodak, or a similar reliably scam-free instruction, before they spend many dollars on equipment and waste silver solutions and then complain that it isn't generating as much silver as they hoped. Good luck. Regards,
