Abstract

a presente invenção se refere a um método para a separação do ferro a partir de uma fase orgânica líquida inicial que contém o urânio e o ferro, em que a fase orgânica líquida inicial é colocada em contato com uma solução aquosa referida como solução aquosa de desferração, em que o ferro passa para a solução aquosa para formar uma fase aquosa líquida final e o urânio permanece na fase orgânica líquida inicial para formar uma fase orgânica líquida final referida como fase orgânica desferrada; dito método sendo caracterizado uma vez que a solução aquosa de desferração contém um ácido inorgânico e o urânio e não contém o ferro. a presente invenção também se refere a um método para a extração de urânio de uma solução aquosa de um ácido inorgânico que contém o urânio e o ferro.The present invention relates to a method for separating iron from an initial liquid organic phase containing uranium and iron, wherein the initial liquid organic phase is contacted with an aqueous solution referred to as aqueous decay solution. wherein iron passes into the aqueous solution to form a final liquid aqueous phase and uranium remains in the initial liquid organic phase to form a final liquid organic phase referred to as deferred organic phase; said method being characterized since the aqueous decay solution contains an inorganic acid and uranium and does not contain iron. The present invention also relates to a method for extracting uranium from an aqueous solution of an inorganic acid containing uranium and iron.
