一般的铜电积涉及水在阳极的分解,槽电压约为2伏。若阳极反应改为SO_2的氧化,槽电压几乎可降低一半,这对水冶过程的总能耗有很大影响。此外,此法生产的硫酸可翻一番,故生产流程中若正确地采用此法,可获双重的好处。具体做法是在 Common copper electrowinning involves the decomposition of water at the anode, and the cell voltage is about 2 volts. If the anode reaction is changed to SO 2 oxidation, the cell voltage can be reduced by almost half, which has a great impact on the total energy consumption of the hydrometallurgy process. In addition, this method can double the production of sulfuric acid, so the correct use of this method in the production process, can have double benefits. The specific approach is
