A titanium or tantalum cathode which has a nickel coat on it is used for the electrolytic recovery of gold from solution. The gold is stripped from the cathode by use of aqua regia which strips the nickel coat but does not affect the underlying titanium or tantalum. The amount of nickel is only enough to prevent destructive hydrogen absorption by the titanium or tantalum and is not enough to ...
