Selective Hydrochloric Acid Leaching of Zinc, Lead and Silver …
Abstract A solid waste from zinc production, zinc plant residue (ZPR) is a valuable resource for the recovery of zinc (Zn), lead (Pb), and silver (Ag). However, the ferritic structure of ZPR makes it difficult to leach these metals. Here, in order to increase the reactivity of the ZPR, mechanical activation using a high-energy ball mill was used. …

Crushing, Grinding and Concentration of the Ore
For example: sodium cyanide can be used as a depressant in the separation of zinc sulphide ore (ZnS) and lead sulphide ore (PbS). Sodium cyanide forms a layer of zinc complex, Na 2 [Zn(CN) 4] on the surface of ZnS and therefore prevents it from forming the froth. Therefore, it acts as a depressant. 4 NaCN + ZnS —–> Na 2 [Zn(Cn) 4] + Na 2 S
