If you accumulate enough copper, and the refine electroloytically, you can recover gold and other precious metals that exist in copper, in small amounts.
Copper refining is a big business, a lot larger than you might think. Problem is, there are only a few big copper refiners, and that entails shipping copper over a long distance to a refiner who will pay out on all values. It would also require properly representing your material at the refiner.
