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 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

Copper Mining and Extraction Sulfide Ores

Pure copper cathodes are arranged between the blister copper anodes and a current of over 200A passes through the solution This is driven by a low voltage of about 1 3V and so the process is safe What happens in electrolysis Under these conditions copper atoms dissolve from the impure anode to form copper ions

copper extraction and purification
