A PROCESS FOR REDUCING THE CONTENT OF OXYGEN IN METALLIC COPPER

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 oxygen through the reduction of CuO to Cu. This way, the purity of the...

description 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 oxygen through the reduction of CuO to Cu. This way, the purity of the metallic copper is increased.
