Solvent extraction fractionation of manganese, cobalt, nickel …
A new solvent extraction process was proposed for the extraction of manganese and cobalt using TODGA extracting agent diluted in a room-temperature ionic liquid. The hydrometallurgical process presented here ( Fig. 1 ), allows first to remove manganese very selectively from the leach liquor using TODGA extractant diluted in an ionic liquid.
