Material resources Copper ore – Hydro route (0.4% Cu, avg.)
The processing of recycled copper requires much less energy than the processing of new copper from ore, providing a savings of 85–90 percent of energy requirements. 5. Ranking only behind Chile in copper production, the United States is largely self-sufficient in copper supply.

Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).

Material resources Copper ore – Hydro route (0.4% Cu, avg.)
Recycling copper uses much less energy, about 10GJ/tonne, that''s only 10% of the energy needed for extraction. This energy saving leads to the conservation of valuable reserves of oil, gas or coal and reduces the amount of CO 2 released into the atmosphere. Conservation of copper ore To date only about 12% of known copper resources have been mined.

Now, researchers at the Department of Energy’s National Energy Technology Laboratory (NETL) believe copper may play an important role in combatting climate change. When used as a part of a promising coal combustion technology known as chemical looping, copper can help economically remove carbon dioxide (CO2) from fossil fuel emissions.

Ores that contain copper in the U.S. are typically mined in large, open-pits. Copper processing facilities are usually located near mining or extraction sites. Significant waste volumes are associated with copper production. Mine wastes may contain radionuclides due to their natural presence in ores and can be a source of TENORM.

Mines are faced with numerous challenges, such as falling raw material prices, declining metal grades in the ores and higher energy prices. Especially because ore processing is particularly energy-intensive, the industry is again focusing on the saving of energy. This report shows what are the key energy saving considerations in the copper and gold mining sectors.

Going forward, the total amount of energy required to produce copper from primary resources will be determined by the future ore grade, energy efficiency, and the process used in copper production. As shown in Fig. 2 (a), the average copper ore grade is expected to decrease in the future as a function of cumulative production.
