Abstract A novel hydrometallurgical process for recovery of palladium and gold from phone components in HCl-CuCl2-NaClO leaching system was offered, different factors of Pd, Au leaching process were investigated. The results of experiment indicated that, on the condition of 2mol/L HCl, 5% NaClO, 0.075mol/L CuCl2 at 333K for 2h with a solid/liquid ratio of 1/100, over 85% of Pd and Au was leached. Cu2+, Cl-, the temperature for the Pd leaching rates played a significant role. NaClO was added to solutions could accelerate the Pd leaching reaction rates; NaClO, the temperature for the Au leaching rates had a significant influence. The additions of HCl, Cu2+ to promotes Au leaching. Therefore, HCl-CuCl2-NaClO leaching system for Pd, Au leaching have a positive effect.
