Overpotential in silver electrolysis

Separation of noble metals is very touchy since they have nearly identical sub-orbitals, and thus nearly identical electrical potentials.

One possible method is going pyro after your electro process and separating the molten silver from the solid gold. If you used ~1000'C for your distillation temp, it would take several steps to obtain a few 9s of purity but the process is simple enough.

Another possible method is selective use of a surfactant and using froth flotation to separate the two prior to electrolysis. The hard part for this would be "cleaning" the surfactant out of solution, but a few simple alcohol washes should get most of it off your particles.

And the last method that I can think of would be controlling your buffer solution within a few hundredths of pH. But not only would this be extremely tedious I also don't think it will do much good since they have the same amount of free electrons and the difference between the orbitals is only 1.

Does anyone know if Mr. Fernandez could create a gold-mercury amalgam in solution, without touching any of the silver?

We refine silver to FIVE 9's plus...one pass....from stirling and lower scrap...our own equipment...different design...different approach...was told it couldn't be done.

Indicate production rate needed...supply e mail address and I'll direct communicate.

MR GUY.

I am so sorry Mr. Guy, but i can not send to you that information because in this moment we done not want to change our process, only we want to solve the problems in our process. But, i would like that you send me information about your company, because in a future we would want to increase capacity.

Thanks
