Paper Title:
Study on Behavior of Impurity Antimony in Zinc Electrowinning
  Abstract

By means of an electrochemical study, the influence of Sb3+ on cathode polarization process in zinc electrowinning and its kinetics equation and parameters have been studied. The results show that antimony has a depolarization function in the presence of [Sb3+] ≥0.5 mg·L–1 in zinc electrowinning, and Sb3+ has a polarization function in zinc electrowinning in the presence of [Sb3+] ≥1 mg·L–1, the polarization curve enters into the hydrogen evolution range from the activation range, which indicates that the presence of antimony has adverse influence on the zinc electrowinning process.
