Discusses an attempt to optimize the operation of an electric furnace slag to be decopperisation suspension of the internal recycling

process for the production of copper. The paper presents a new method to recover copper from metallurgical slags in arc-resistance electric

furnace. It involves the use of alternating current for a first period reduction, constant or pulsed DC in the final stage of processing. Even

distribution of the electric field density in the final phase of melting caused to achieve an extremely low content of metallic copper in the

slag phase. They achieved by including the economic effects by reducing the time reduction.
