How do you separate gold from the metals it is made with and or overlays like jewelry contacts tin copper etc? HELP
How do you separate gold from the metals it is made with and or overlays like jewelry contacts tin copper etc like gold plated terminals? with acids or with out acids. I HAVE ABOUT 10LB OF GOLD PLATED CONNECTORS.
The easy way is with concentrated nitric acid, e.g. "the acid test".
It's not something you should try at home in the kitchen sink. there will be fumes, and corrosion.
There are cyanide compounds that combine with gold, but you probably don't want to mess with that, either.
I am aware of electrochemical refining, which is still messy, or you can get a special kiln that gets hot enough melt gold and burn off all the plastic and stink up the neighborhood.
Unfortunately the gold plating on your electrical connectors may be quite thin, only a few molecules deep. Your best bet may be to sell them "as is" to an optimist.
