I had a bead that compose of approx.70 percent copper and 15% silver and 5% gold
How can i seperate the gold ?If i piut the bead in 50/50 nitric acid the copper will dissolve
But will the silver dissolve too? Wont it be push out by the copper ions in the nitrate solution ?
Because of the electromotive series copper will push out/ cement the silver because they are in the same solution with
The copper, is there a way that copper and silver will be dissolve andleft the 5% gold
In the solution? .. i mean i only wanted the gold... kindly advise me what to do
I didn't find the right solution from the Internet.
