As a key material for semiconductors, photovoltaic devices, and infrared detectors, the high⁃qualitypurification technology of scattered metal tellurium（Te）directly affects the performance and reliability of downstreamproducts. The research progress of mainstream purification processes was systematically reviewed, including chemicalpurification（chemical precipitation, solvent extraction, electrorefining, and hydrogenation）and physical purification（vacuum distillation, zone melting, Czochralski purification, and solid⁃state electromigration）. The applicable scope,advantages, disadvantages, and existing problems of each process were thoroughly discussed, and prospects for futureresearch priorities in high⁃purity Te preparation were provided. The aim is to promote the optimization and developmentof high⁃purity Te preparation technology through a comprehensive review, establish an efficient, low⁃consumption, andsafe Te purification system, and provide core material support for the new generation of electronic information andclean energy industries.
