بیشترInformation on the recycling rates of the remaining 80% of rhenium products is quite limited, although it is postulated to be sufficiently lower than the Pt-Re catalyst industry. Thus, the largest area for potential research may be the recovery and subsequent reuse of the rhenium in superalloys and various rhenium containing products.

بیشترW-1% Re specimen in another study showed similar result to this irradiated pure tungsten. The transmuted amount of rhenium was calculated to be about 0.52% for these specimens, and that shows good agreement with this study. Further more, annealing beyond the irradiation temperature, up to 800 °C resulted in no recovery of thermal diffusivity.
بیشترRhenium was also recovered efficiently and selectively from rhenium–tungsten solutions (initial concentration 10.4 mM for each metal): when the pH ranged from 7.0 to 12.0 and the irradiation time was 6 h, the rhenium recovery was 90–95% and the rhenium recovery ratio was 7.3–45 times that of …
