BBC - GCSE Bitesize: 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. Copper is purified by electrolysis.
