How Copper is Extracted and Processed From Ore to Metal. The extraction of copper typically starts with mining copper ores, such as chalcopyrite, the most common copper ore. These ores are then refined to extract copper. The process involves crushing the ore, grinding it, and using flotation to separate copper from other materials in the ore.
Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and …
