Abstract:  As a kind of rare and dispersed non-metallic elements in nature， selenium and tellurium are widely used in metallurgy， chemical industry， information， energy and electronics due to their excellent physical and chemical properties such as oxidation resistance， strong photosensitivity and good plasticity. And with the increasing scope of applications， the amount of use has increased significantly. Due to the associated properties of selenium and tellurium resources， the production is restricted by the production of the main minerals that it will become increasingly difficult to meet the current market demand while leading to conflicts between supply and demand and will also face the problem of resource shortage. The comprehensive utilization of renewable selenium and tellurium resources will become a research hotspot.This paper briefly described the current resource reserves， applications， and consumption of selenium and tellurium. It classified and summarized the treatment technology of various types of primary and renewable raw materials of selenium and tellurium， and emphatically described the extraction process of selenium and tellurium with copper anode slime as the representative raw material， and detailed introduced the advantages and disadvantages of different treatment technologies and progress. In the end， the future development direction of selenium and tellurium resource recycling is forecasted.
