SIMULTANEOUS OXIDATION AND STRIPPING FOR SEPARATING SE AND TE FROM SULFUR - RESEARCH SUMMARY

Sulfur as a potential by-product of hydro-metallurgical processes cont ains 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 se lenium and tellurium from sulfur in acidic solutions can be achieved p rovided 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.
