Abstract:In this study, a solvometallurgical process for the recovery of Cu from industrial dust by leaching with a lixiviant comprising hydrochloric acid (HCl) and ethylene glycol followed by extraction with trioctylphosphine oxide (TOPO) was developed. Copper, Ni, Mg, and Al contained in the dust were efficiently dissolved by using HCl in ethylene glycol, leaving most of the Ag in the residue. The parameters (concentration of the lixivant, reaction temperature, pulp density) that affect leaching efficiency were exten… Show more
