Simultaneous oxidation and stripping for separating Se and Te from sulfur
- 33 Downloads
Sulfur as a potential by-product of hydrometallurgical processes contains selenium and tellurium as impurities. These impurities have to be removed if the sulfur is to be marketable. While selective reduction of selenium from sulfur is not realized, the selective oxidation of selenium and tellurium from sulfur in acidic solutions can be achieved provided that proper contact of selenium and tellurium with the oxidant is available. Simultaneous oxidation and stripping has been employed to separate selenium and tellurium from the sulfur in this study.
