The copper production process involves several steps. Mining extracts the raw copper ore from the earth. Crushing reduces the ore's size for easier processing. Concentration separates the copper-bearing minerals from waste rock. Smelting melts the concentrated ore to extract the copper. Refining purifies the copper to a high level of purity.
