Description: Production of cathode copper by electrolytic refining.

Comment: The multi-output-process "secondary copper refining" delivers the co-products "precious metals from electric waste, in anode slime, at refinery", "copper, secondary, from electronic and electric scrap recycling, at refinery" and "nickel, secondary, from electronic and electric scrap recycling, at refinery". The product "precious metals from electric waste, …" is an intermediary in the production of secondary gold from electric scrap and is not to be used by the LCA practitioner. The flows "copper, …" and "nickel, …" are by-products of this process that receive part of the burdens allocated. They must not be used. [This dataset was already contained in the ecoinvent database version 2. It was not individually updated during the transfer to ecoinvent version 3. Life Cycle Impact Assessment results may still have changed, as they are affected by changes in the supply chain, i.e. in other datasets. This dataset was generated following the ecoinvent quality guidelines for version 2. It may have been subject to central changes described in the ecoinvent version 3 change report (http://www.ecoinvent.org/database/ecoinvent-version-3/reports-of-changes/), and the results of the central updates were reviewed extensively. The changes added e.g. consistent water flows and other information throughout the database. The documentation of this dataset can be found in the ecoinvent reports of version 2, which are still available via the ecoinvent website. The change report linked above covers all central changes that were made during the conversion process.]
