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 ....Know More
Ore Grade The costs of mining and processing copper are more closely related to the gross tonnage of the ore than the net tonnage of copper in the ore5 A tonne of lean ore requires no more capital, energy, labor, and supplies to mine than a tonne of rich ore However, because the rich ore con-tains more copper, it requires less of these inputs...Know More
