A method for extracting and recovering tantalum present in an acidic aqueous phase by means of an ionic liquid and the use of such an ionic liquid for the extraction of tantalum from an acid aqueous phase
A method for extracting and recovering tantalum present in an acidic aqueous phase by means of an ionic liquid and the use of such an ionic liquid for the extraction of tantalum from an acid aqueous phase
The present invention relates to a process for the extraction of tantalum from an acid aqueous phase A1, said process comprising contacting said aqueous phase A1 with phase A2 which is not miscible with water, And separating said phase A2, said phase A2 being formed by a mixture of ionic liquids or ionic liquids as an extracting agent. The present invention also relates to a method for recovering tantalum using this extraction method and also for the use of a mixture of ionic liquids or ionic liquids as an extractant for the extraction of tantalum from such aqueous phase A1.
