Provided is a method for producing cathode copper. The method comprises a smelting step including feeding sulfidic copper bearing material and oxygen-bearing reaction gas into a suspension smelting furnace, to produce blister copper, a fire refining step including feeding blister copper into an anode furnace to produce molten anode copper, an anode casting step to produce cast anodes, a quality checking step for dividing cast anodes into accepted cast anodes and rejected cast anodes, an electrolytic refining step including subjecting accepted cast anodes to electrolytic refining in an electrolytic cell to produce cathode copper and as a by-product, spent cast anodes, and a recycling step for recycling anode copper of rejected cast anodes and anode copper of spent cast anodes. |
