Lixiviación de Pb y Zn empleando el sistema Tiourea-EDTA [PDF]
, 2022 Mining tailings stored in tailings dams generally contain sulfides such as galena (PbS) and sphalerite (ZnS). To prevent Pb and Zn from being released by weathering, the (TU) (CH4N2S)-EDTA (C10H16N2O8) system was proposed to carry out the leaching of ...
