In thecondition of venting air and adding SO_3~(2-), the consumption of SO_3~(2-) is about 40 percent,while the concentration of S_2O_3~(2-) increased by 76 percent, which compensated the loss ofS_2O_3~(2-) and make the gold leaching system more stable.

• 在通空气，加 SO_3~(2-)的情况下，SO_3~(2-)消耗40%25，而 S_2O_3~(2-)浓度增加76%25，弥补了S_2O_3~(2-)氧化造成的损失，使浸金成分稳定；
