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 pyrometallurgy respectively due to the different
