I've been purifying adulterated silver that consists of 75% silver and remaining 25% includes copper, zinc, gold etc, using acids and now I would like to do the same in an easy way. If there is somebody to guide me to do the same using electrolysis method kindly guide me.

purification of silver containing zinc , copper , gold using electrolysis
The impure silver is made the anode while a thin sheet of pure silver acts as cathode.
The electrolytic tank contains a solution o silver nitrate acidified with 1% nitric acid
On passing electricity , pure silver gets deposited at the cathode
at anode : Ag ---------> Ag+ + e-
at cathode : Ag+ + e- ---------> Ag
Zinc , Copper pass into the solution as soluble salts
Gold collects under the anode as anode mud
