| titleOfInvention | How to recover tellurium |
| abstract | (57) [Problem] To recover tellurium from copper telluride generated in a treatment process of anode mud in copper electrolytic refining at low cost. SOLUTION: The weight ratio of copper telluride is 0.26-1. By adding and heating 20 times the amount of sulfur, the tellurium of copper telluride is replaced with sulfur, and a mixture of copper sulfide and tellurium is generated. After evaporating and separating excess sulfur from the mixture and heating the mixture to 200 to 1000 ° C. under reduced pressure, only tellurium is vaporized, and high-purity tellurium is aggregated in the cooling part. Copper sulfide, a by-product, is reused as a raw material for smelting copper. |
