Where does the copper used for wiring and plumbing come from?

Question

Quizplus · Accepted Answer

Most copper used for wiring and plumbing comes from mines in the ground, as the ore is typically found in large deposits underground. While copper can also be found along riverbanks, it is generally a smaller source and not sufficient for industrial purposes. Copper is not typically found in significant amounts in ocean sediments, and while it can be recycled and manufactured synthetically, this process is not typically used for industrial scale copper production.
