| description | The invention relates to a method for recovering metal tellurium from tellurium-containing waste through vacuum fractional condensation. The method belongs to the technical field of pyrometallurgy andresource regeneration of non-ferrous metals, and comprises the following steps: placing tellurium-containing waste in a vacuum fractional condensation furnace, vacuumizing, heating to a certain temperature, carrying out vacuum thermal decomposition, adjusting the temperature, carrying out fractional condensation, carrying out heat preservation for a period of time, and stopping operation to respectively obtain metal tellurium and other valuable metals; the method is simple in process, convenient to operate, simple in required equipment, free of generation of waste water and waste gas, low incost, high in universality of raw materials, capable of treating tellurium-containing waste materials with any components, and safe and controllable in process.
