Copper Mining Methods

The heavy copper plates that have been shaped are called anodes In the final extraction steprefiningany remaining minor impurities are removed from the anodes The result is almost 100 percent pure copper This metal will be sent to other plants to be made into products such as copper pipe and copper wire
