Copper, Chemical Element

The most common method for copper purification relies on electrolysis, which is the process by which an electrical current is used to cause a chemical change, usually the breakdown of some substance. The copper is dissolved in sulfuric acid again and an electric current is passed through the solution.

The blister copper is already virtually pure (in excess of 99% copper). But for today's market, this is not really pure enough! It is purified further using electrolysis. This is known as electrolytic refining. The blister copper is cast into large slabs which will be used as the anodes in the electrolysis apparatus.

The copper is then melted and purified in several stages until it is 99% pure copper. At this point it is cast into anodes. Oxygen remains in the structure as cuprous oxide, Cu2O. The majority of the structure is pure copper. The copper metal solidifies from the liquid state by the growth of crystals.
