A copper smelting process is disclosed in which copper concentrate is smelted in a furnace to produce purified copper. Flue gas discharged from the furnace is treated to produce sulfuric acid. Furthermore, waste liquid discharged during the production of sulfuric acid is treated to produce gypsum, and the gypsum thus produced is recycled to the furnace as a flux.
