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.
