Plating From Waste Photographic Chemicals
"Recovering Silver from

Could you explain how I can silver plate straight from waste photographic chemicals. I would like to try plating flowers and other small items; which is the best way to remove a small amount of silver from the chemicals and refine it, as I don't have easy access to a silver recovery unit and the chemicals are stored for months at a time.Debbie Paterson

Well Debbie, it is much more involved than a person would think.
First, there probably is not enough silver in solution (small amount) to electroplate.
Second, the pH would not be correct I believe. Cyanide is the best known additive for silver plating. There are non-cyanide processes out there, but proprietary additives are used. The flowers would have to be coated with a conductive coating first. Then copper applied.
Something to consider: be aware people have been killed from toxic fumes attempting to recover silver from these type of solutions.Bill Hemp
