| 摘 要： | 先通过脱除铜阳极泥加压浸出液中大部分的铜离子，再进行分步还原分离硒、碲，进而达到高效分离硒、碲的目的，硒、碲分离率＞98%。该方法解决了铜阳极泥加压浸出液在沉硒过程中硒不能完全沉淀、影响硒的直收率指标、后续沉碲尾料中硒含量偏高不利于碲精炼提取的问题。

| 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. |

| Keywords: | copper anode slime pressure leaching solution selenium tellurium separation |
