Abstract

PROCEDIMIENTOS PARA LA OBTENCION DE FOSFATOS Y DE UN CONCENTRADO QUE CONTIENE URANIO A PARTIR DE ACIDO FOSFORICO POR VIA HUMEDA. SE TRATA EL ACIDO FOSFORICO CON UN COMPUESTO DE FLUOR INORGANICO EN PRESENCIA DE UN DISPERSANTE ORGANICO DE UN AGENTE REACTOR. A CONTINUACION SE SEPARA EL PRECIPITADO RESULTANTE, QUE CONTIENE URANIO Y SE RECUPERA EL DISPERSANTE DE LA MEZCLA DE ACIDO FOSFORICO, DISPERSANTE Y AGUA. PARA LLEVAR A CABO LA RECUPERACION DEL DISPERSANTE SE AÑADE A LA MEZCLA UN COMPUESTO QUE REACCIONA CON EL ACIDO FOSFORICO PARA FORMAR UN FOSFATO INSOLUBLE EN LA MEZCLA DISPERSANTE-AGUA, SEPARANDOSE DICHO FOSFGATO POR PRECIPITACION.
