Copper Mining and Processing Processing of Copper Ores

Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 9999% 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
