As estimated, the investment and operation costs of this process are around 20% less than that of the traditional processes. (3) Accurate control over material/oxygen ratio ensures the furnace contains only two melt phases – slag and crude copper – and no cuprous sulfide, and ed slag is not likely to be generated.
