Copper recycling and sustainability Benefits of recycling

In order to extract copper from copper ore the energy required is approximately 100GJ/tonne. 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.

GCSE CHEMISTRY Extraction of Copper Thermal

Extraction of Metals. Extraction of Copper.. Copper is sometimes found as native metal.. Copper ores include copper(II) oxide and copper(II) sulfide. Copper(II) oxide can be reduced by reaction with carbon.. Some copper ores may contain only small amounts of copper. These are called low grade ores and have less than 1% copper but they are still used because copper is so valuable.
