| Abstract: |
| Most of copper ions in copper anode slime pressure leaching solution were firstly removed, and then selenium and tellurium were separated by reduction step-by-step. Separation rate of selenium and tellurium is both above 98%. This method solves the problems that selenium cannot completely be precipitated from copper anode slime pressure leaching solution during selenium precipitation process, and high selenium content in subsequent settling of telluride is not conducive to refining and tellurium extraction. |
