Silver electrorefining Ok, so let's say I have raw silver which is polluted with a bit of gold, copper and lead.
So through electrorefining I want to make pure silver out of it.

Let's say I have it all in an acidic solution. What happens when I turn on the Voltage?
How would I prevent the other elements from getting electrolyzed?
Because when I have the electrorefining of copper it gets clean even when polluted with silver, so why doesn't the copper get electrolyzed as well?
It depeds on the acid. If it is HCl then you will get Wohlwill Process only the silver will be not disolved. So baisiclly what you want.
