Current Energy Requirements in the Copper

2013-12-20  In mining copper ore the greatest energy consumers are ore hauling and blasting. Another important factor is the “recovery efficiency” of the metallurgical processes used to extract the copper. The mining and mineral concentrating energies are directly proportional to the “recovery efficiency,” with a typical mining operation requiring about 20 million Btu/ton of cathode copper produced.
