Graphite electrodes are used in the electric furnace for copper scrap melting to produce new copper products such as wires, tubes, and sheets.
Graphite electrodes are used in the anode furnace of copper electrolysis to produce high-purity copper cathodes.
Graphite electrodes are used in the smelting furnace for copper concentrate refining, where the copper sulfide concentrate is melted and converted into blister copper.
