| titleOfInvention | A kind of method for extracting tellurium from tellurium-containing alkali leaching residue |
| abstract | The present invention provides a method for extracting tellurium from a tellurium-containing alkali leaching residue, which comprises the following steps: S1, adding water to the tellurium-containing alkali leaching residue to make a slurry; The leaching reaction is performed to obtain a leaching solution; S3 adds a reducing agent to the leaching solution of S2 for reduction to obtain tellurium powder; S4 casts the tellurium powder of S3. The recovery rate of tellurium reaches more than 98%, the purity of tellurium reaches 99.9%, and the process is short, the efficiency is high, and the waste water is produced less, and the environmental protection effect is good. |
