A process for reducing the content of oxygen in metallic copper

The content of oxygen in molten metallic copper is reduced during the copper refining process by adding pure carbon monoxide, produced by electrolysis of carbon dioxide in a solid oxide electrolysis cell (SOEC), thereby removing oxy- gen through the reduction of CuO to Cu. This way, the pu- rity of...

Zusammenfassung:	The content of oxygen in molten metallic copper is reduced during the copper refining process by adding pure carbon monoxide, produced by electrolysis of carbon dioxide in a solid oxide electrolysis cell (SOEC), thereby removing oxy- gen through the reduction of CuO to Cu. This way, the pu- rity of the metallic copper is increased.
