Solvent extraction was investigated to separate Mo(VI), V(V), Re(VII), and W(VI) from synthetic solution with a pH range 2–10. Both Mo(VI) and V(V) were selectively extracted by LIX 63 from the solution with an initial pH of 2. The W(VI) in the raffinate was selectively extracted over Re(VII) by Alamine 336. Extraction and stripping conditions were obtained to propose a separation process.
