how to separate gold from copper

How I can separate gold from copper?

To transmute copper to a stable form of gold, it would be necessary to add a lot of protons and neutrons to the nucleus of copper, 50 protons plus 64 or 65 neutrons. Changing the nuclear structure of elements requires a fusion process where the energy required is found in stellar fusion and collisions ( the stars)… even the stars do not synthesize gold directly from copper.
