Abstract
Provided is a method for melting copper scrap and/or refining blister copper, comprising the steps of: (a) charging of copper scrap into an empty anode furnace and melting the copper scrap; (b) charging molten blister copper into the anode furnace; (c) optionally charging more copper scrap into the anode furnace and melting the copper scrap; (d) optionally repeating steps (b) and/or (c) one or more times until the anode furnace is full and a desired amount of copper scrap has been charged and melted until a final copper batch is obtained; and (e) refining the final copper batch to obtain anode copper.
