Letter 10011 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. MAROUKY RIDA Pariod - Benghazi, Libya   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 Maroky Rida Paroid - Benghazi, LIBYA June 1, 2006 I HAVE FIXED/HYPO SOLUTION CONTAINING SILVER.

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, Santosh............. Santosh ekbote chemical - Pune,Maharshtra,India December 29, 2006 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! Ted Mooney, P.E.  finishing.com Brick, NJ

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 mathod 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 extrate this silver from this expired x-ray films and the waste fixer solutions very profitably?
Can i get a pure 100% silver?
thank you
