摘　　要：硒、碲作为自然界中含量稀少且分散的非金属元素,因具备抗氧化、光敏性强以及良好的塑性等优异的物理化学性能,被广泛应用于冶金、化工、信息、能源及电子等工业领域,并随着应用范围日益扩大,用量大幅度增加。由于硒、碲资源伴生属性,产量受主矿种生产制约,将越来越难以满足当前的市场需求,导致供需矛盾突出,同时也将面临资源短缺问题,再生硒、碲资源综合利用将会成为研究的热点.总结了当前硒、碲的资源储量、应用和消费概况,分类归纳了各类硒、碲原生及再生原料处理工艺技术现状,重点阐述了以铜阳极泥为代表原料的硒、碲提取工艺,并详尽介绍了不同处理工艺的优缺点,最后对硒、碲资源回收利用的未来发展方向进行了展望。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.
