| Abstract: | The methods of extracting and refining tellurium presently were mainly soda roasting,autoclaving in general basic solution,sulfating roasting,oxidative leaching in acid solution,solvent extraction,emulsion liquid membrane,microbial method,electrorefining,vacuum distillation and zone melting etc.The tellurium using electrorefining was 99.99% and the vacuum distillation refining was 99.999%,but the tellurium of zone melting refining can reach 99.999995%.In the paper the methods of extracting and refining tellurium were summarized respectively. |
