Process and Installation for reextraer in several successive steps of a Uranium extractant

摘要

Process and Installation for the reextraccion in Successive stages of uranium, an extractant, consisting of an acid and a dialquilfosforico trialkylphosphine oxide dissolved in an organic Solvent miscible with water.The extractant is treated with an aqueous solution of Phosphoric Acid containing ferrous ions; separate the Organic phase in the aqueous phase of impoverished Uranium enriched in the metal; Recycle a fraction of this aqueous Phase Enriched towards the first stage; and adjust the contents Or ferrous ions from the aqueous Phase by the Recycled fraction enriched in Uranium in contacWith Metallic Iron, so that the metal is in Motion relative to the aqueous phase to create an abrasion of the same.
