Abstract

Procédé d'extraction au solvant, à contre-courant à plusrieurs étages, pour la séparation de cobalt de solutions aqueuses de sulfate contenant du calcium à saturation, dans lequel on utilise un acide phosphinique organique soluble comme agent d'extraction, le pH dans les différents stades du procédé étant controlé de manière à réduire au minimum le dépot de gypse dans l'équipement d'extraction.
