The results of rhenium (VII) solvent extraction with synergistic mixtures of octyl alcohol and ketone from the high acid chloride and sulphate solutions with high accompanying metals (platinum and molybdenum) content, obtained from leaching of rhenium-containing wastes, were presented. It is shown that synergistic coefficients at rhenium solvent extraction by mixtures of 30–50 % v/v 2-octanol in 2-octanone were not exceeded 1.2–1.3. However, such mixtures recovered fewer impurities of Pt (IV) and Mo (VI), and the separation factors reached 16.0 and 573.2. Besides, mixtures of alcohol and ketone are characterized by higher rhenium (VII) capacity than the alcohol alone.
