| Abstract: |
| The natural chalcopyrite was selected as the research object;the electrochemical behavior of the effect of chlorine ions on the solution of chalcopyrite during the oxidic-acidic leaching by the three-electrode method was studied. The results show that the chlorine ion can't change the potential of the solution,but can improve the leaching rate of the chalcopyrite and restrain the wrap of sulfur.The anodic peak of H_2S was also detected in these tests,which deduce that H_2S is formed during the acid oxidative leaching of chalcopyrite. |
