In conventional hydrochemical iridium refining the scrap is alloyed with nickel to form a 70Ni-30Ir alloy by melting and the iridium is recovered as an impure powder (70Ir-30Ni) by acid leaching of this alloy. The iridium powder is then subjected to

Melt refining of transuranic contaminated metals is a possible decontamination process with the potential advantages of producing metal for reuse and of simplifying chemical analyses. By routinely achieving the 10 nCi/g (∼0.1 ppm) level by melt ref
