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.

Electrolytic refining (electrorefining) is a process used to make impure copper pure. Unlike aluminum, copper metal is fairly easy to obtain chemically from its ores. By electrolysis, it can be refined and made very pure—up to 99.999%. The electrorefining is at the heart of not only copper purification, but the production of sodium hydroxide

The process of extracting copper for its ore is quite complex and varied. It largely depends on the type of ore in question, particularly whether it is a sulfide or oxide type. Copper mining has typically been performed through open-pit mining, where stepped benches are dug deeper and deeper into the ground over time.

In most cases, the thin-layer process was used where crushed ores (80% −0.5 in) were stacked in heaps of 3–8 m height after agglomeration and sprayed at flow rates of 6–40 L·hour −1 ·m −2 with 15–90 days duration for copper oxides and 10–18 months for sulfides. Of note, 80%–85% copper extraction was commonly achieved.
