recovery technique of Sc was complicated and the chemical consumption was high, This was due to the low content of Sc in resources and the difficulty of stripping. In this research, the isooctanol was added into the 2-ethylhexyl phosphonic acid mono-2-ethylhexyl ester(P507) extraction system to reduce the extraction and improve the stripping of Sc. The maximum stripping ratio of Sc from loaded......

be stripped efficiently by the moderately strong NaOH solutions (0.5-1.0 mol/L) and the presence of NaCN in the stripping solution facilitates copper stripping. Key words: copper; cyanide; solvent extraction... cyanide solution. It was found that the solvents from different temperature tests exhibited the similar extraction capability for copper and cyanide after stripping, indicating that the functionality......
of(RO)2P(O)OPh-COOH as carrier, polyisocrotyl succinimide(T154) as surfactant, sulfonated kerosene as diluent, phosphoric acid(H3PO4) as stripping solution. Different chemical parameters such as type and concentration of carrier, surfactant, stripping solution, volume ratio of oil phase to internal phase, and volume ratio of emulsion ratio to external phase were analyzed. The extraction of RE3......
