At the second stage, the recovery of lead from a zinc leach residue of an oxidic ore was investigated through batch flotation studies. The residue was leached with water before sulfidization to eliminate its soluble compounds.
view moreZinc leaching residue is a good source of zinc and has a great potential to be utilized. However, it is very difficult to recover lead, zinc and silver from the residue by traditional technologies. In this study, a new technology based on conversions of PbSO4 and ZnSO4 in the residue to their respective sulfides by reduction roasting with coal powder followed by …
