Flotation method for separation of elemental Te with Se as

A method combining co-precipitation of traces of elemental Te on Se as carrier with organic solvent flotation is described. The best reduction and flotation conditions (hydrochloric and phosphinic acid concentrations, amount of Se, solvent used) were chosen. The recoveries for 100μg of Te(IV) (AAS measurement in MIBK) and 2μg of Te (radiochemical measurement with127Te) were 98% and 84–88%
