Zinc in dust can also be leached out by organic acids. Zhang et al. found that when the BF dust was leached by 0.2 mol/L iminodiacetic acid at 20 °C with a liquid–solid ratio of 10 for 2 h, the leaching rate of zinc in the dust could reach 62.78% . Zinc in the leaching solution can be separated by adding a chemical precipitator.
