What are some ways to extract copper from copper oxide?Extraction and purification of copper. Copper is less reactive than carbon, so it can be extracted from its ores by heating it with carbon. For example, copper is formed if copper oxide is heated strongly with charcoal which is mostly carbon: copper oxide + carbon copper + carbon dioxide.

Poling (metallurgy) A metallurgical method employed in the purification of copper which contains copper oxide as an impurity and also in the purification of tin which contains tin oxide (stannic oxide or "SnO 2") as an impurity. The impure metal, usually in the form of molten blister copper, is placed in an anode furnace for two stages of refining.

Copper extraction Copper can be lost from the matte in three ways: as cuprous oxide (Cu 2 O) dissolved in the slag, as sulfide copper dissolved in the slag or as tiny droplets (or prills) of matte suspended in the slag. The amount of copper lost as oxide copper increases as the oxygen potential of the slag increases.
