Copper extraction - Wikipedia

Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).

Copper extraction - Academic Kids

Jun 18, 2005  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.

Copper - Essential Chemical Industry

Secondary production. Copper and alloys with a high copper content are recycled to obtain pure copper. The metals are heated with oxygen-enriched air, which oxidizes most of the metals, but not the copper or any precious metals, forming a slag that can be removed. The Isasmelt process described above is often used for secondary copper production.
