lead zinc leaching

  • Lead and zinc selective precipitation from leach electric ...

    However, the zinc content of these dusts is usually low compared with iron and only a small fraction of the zinc can be extracted without leaching iron, lead and elements such as Ca, Fe and Mg. As a result, a large quantity of extra acid will be consumed and a leach solution with complex components will be obtained .

      Lead, but not zinc, was totally removed by EDTA treatment (1200 mg L1, pH 6.0). Ultrasound treatment was ineffective in metal leaching at all tested pH values, either with or without EDTA addition, probably because of the reduction in size of the carbon particles and the concomitant increase in surface area available for metal binding.
