Copper extraction - WikipediaIf the ore is primarily sulfide copper minerals (such as chalcopyrite), the ore is crushed and ground to liberate the valuable minerals from the waste ('gangue') minerals. It is then concentrated using mineral flotation. The concentrate is typically then sold to distant smelters, although some large mines have smelters located.Processes - copper mining and production - European Copper InstituteCopper is found in natural ore deposits around the world. This page explains the copper mining and production route from ore-containing rock to a final product that is the highest-purity commercial metal in existence, used in a wide variety of applications essential to modern living.
