Copper - Department of EnergyThe two major processes employed in the United States to recover copper from ores are classified as either (1) pyrometallurgical methods (copper processing), or (2) hydrometallurgical methods (copper beneficiation). Pyrometallurgical methods consist of smelting technology, and are widely used. Hydrometallurgical.Copper - Princeton UniversityAll aspects of copper production require energy, whether i n the form of electricity, explosives, or hydrocarbon fuels (diesel, gasoline, natural gas, fuel oil, coal, coke), or as the energy equivalent of materials consumed (e. g., chemicals and steel grinding media). In 1977, the primary copper in- dustry purchased 121 trillion.


Current Energy Requirements in the Copper . - Springer Link

SUMMARY. An analysis of energy usage in the production of refined cathode copper was made from mining ore to cathode copper. In mining copper ore the greatest energy consumers are ore hauling and blasting. Another important factor is the "re- covery efficiency" of the metallurgical processes used to extract the copper.

Copper Smelting - IFC

Copper can be produced either pyrometallur- gically or hydrometallurgically. The hydromet- allurgical route is used only for a very limited amount of the world's copper production and is normally only considered in connection with in- situ leaching of copper ores; from an environmen- tal point of view, this is a questionable.
