Peeling silver off from copper powder


2002

I'm chemist (researcher) of small company. I'm looking for the method which can peel off silver from copper powder (silver coated copper powder). I want an economical method....(not expensive)

Thank you for reading.

Gyu-Sik KIM: You can't peel off silver from silver coated copper. You have to dissolve the powder in nitric acid to get back the silver.

Hi Kim,

Try coating the copper powder with egg albumin before the silver plating.
