Abstract
Solvent extraction applied to refining process for PGMs offers several advantages over the traditional precipitation methods and distillation. Solvent extraction efficiency of Rh and Ru from chloride solutions is very low among PGMs. Therefore, the development of extractants capable of efficiently extracting Rh and Ru is also being studied. However, the current situation is that there are no extractants that can be used industrially. The extraction of Rh and Ru can be improved by forming the extraction-active anion complexes with Rh and Ru by adding Sn (II) to chloride solutions. The authors have previously studied solvent extraction of Rh and Ru with tertiary amine and quaternary ammonium salt from chloride solutions added Sn (II) and shown that the effect of addition of Sn(II) on extraction of Rh and Ru is effective.
