Abstract
Procedimiento para la recuperación de valores de uranio, a partir de una fase extractante orgánica cargada de uranio, que contiene una amina capaz de formar un complejo que contiene uranio y soluble en la fase extractantes orgánica, procedimiento que comprende el poner en contacto la fase extractante, en una pluralidad de etapas de aislamiento, con una fase de aislamiento son pasadas en equicorriente a través de una pluralidad de etapas mezcladoras, sucesivamente de una etapa mezcladora a la siguiente, mientras se agita las fases en cada etapa mezcladora para mantener en ella una dispersión de gotas de una de las fases dispersas en la otra, siendo las gotas de un tamaño tal que el reposo la dispersión se separa substancial y completamente por gravedad en dos capas separadas, pasando a continuación la dispersión de la etapa de mezclado final a una etapa de decantación final para permitir la separación de las fases, y porque el ph de la primera etapa de mezclado es mantenido a un primer valorpredeterminado, que permite el aislamiento de valores de uranio de la fase extractante, mientras que el ph en la etapa de mezclado subsiguiente, o en al menos una de ellas, es mantenido a un valor más alto que el primer valor predeterminado, pero inferior a aquel a que se produce la precipitación de los valores de uranio.
