Currently, the most common source of copper ore is the mineral chalcopyrite (CuFeS 2), which accounts for about 50% of copper production.The focus of this article is on the process of copper extraction from chalcopyrite ore into pure metal. Processes for other minerals are mentioned. For economic and environmental reasons, many of the byproducts of extraction are reclaimed.
