Leaching Behavior of the Main Metals of Decopperized Anode Slime
https://doi.org/2024) 41:2717–2727
Abstract
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 effi cient one-step separation of the scattered and precious metals (SPMs)
from base metals. The result shows that the leaching effi ciencies 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.
