  • Process for extracting and recovering tantalum present in an acid aqueous phase by means of an ionic liquid, and use of such an ionic liquid for extracting the tantalum from an acid aqueous phase
    Patent number: 10844459
    Abstract: A method for extracting the tantalum from an acid aqueous phase A1 comprising at least one step comprising the bringing of the aqueous phase A1 into contact with a phase A2 not miscible with water, and then the separation of the aqueous phase A1 from the phase A2, the phase A2 consisting of one ionic liquid or a mixture of ionic liquids as an extractant. A method for recovering the tantalum that implements this extraction method and to a use of an ionic liquid or of a mixture of ionic liquids as an extractant, in order to extract the tantalum from such an aqueous phase A1.
