Extraction of Copper

A way of extracting the copper from the minerals from underground was eventually discovered. It involved roasting the sulphide minerals in the air, which converted the elements to their oxides: CuS(s) + 1.5O2 (g) CuO(s) + SO2 (g) The metal oxide can then be reduced to just the metal.

Mining and Extraction: Oxide Ores

Copper is refined from ores in the ground, either through underground or open-pit mines. Most of the copper ores mined today are oxide or sulfide ores. Extraction of sulfide ores is covered in more detail in Copper Mining and Extraction: Sulfide Ores (11–14), but is introduced here because an important by-product of this process is used for the extraction of oxide ores.
