Clarifying the occurrence state and embedding characteristics is the primary task to investigate the leaching behavior of the main metals in decopperized anode slime. Electron probe microanalysis, thermodynamic analysis, and leaching experiments were used to determine the optimum conditions for efficient one-step separation of the scattered and precious metals (SPMs) from base metals. The result shows that the leaching efficiencies of Te, Au, Pt, and Pd were 97.69%, 100.79%, 94.47%, and 100.38%, respectively. Moreover, there was scarcely leaching of Pb, Sn, Sb, and Ag, with most of Bi and As remaining in the residue. Te, Au, Pt, and Pd enriched in a targeted manner. This work presents that it is useful in the analysis of the phenomena in copper anode slime hydrometallurgy and provides a short process technology for treating the decopperized anode slime.
