Pyrometallurgical extraction The following is a process of copper extraction from chalcopyrite ore into pure metal While oxide ores can be processed using pyrometallurgical techniques hydrometallurgical methods are more cost effective The copper ore is crushed and ground before it is concentrated to between 20 and 40 copper in a flotation Copper processing is a complicated process that begins with mining of the ore less than 1 copper and ends with sheets of pure copper called cathodes which will ultimately be made into products for everyday useThe most common types of ore copper oxide and copper sulfide undergo two different processes hydrometallurgy and pyrometallurgy respectively due to the different
