The present invention provides 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. 本发明提供种熔融铜废料和/或精炼泡铜的方法，包括以下步骤：(a)将铜废料装入空的阳极炉中并熔融铜废料；(b)将熔融的泡铜装入阳极炉中；(c)任选地将更多的铜废料装入阳极炉中并熔融铜废料；(d)任选地重复步骤(b)和/或(c)次或多次，直到阳极炉充满，并且已装入并熔融所需量的铜废料直到获得最终的铜批料；以及(e)精炼最终的铜批料以获得阳极铜。
