Abstract
PROCEDIMIENTO DE EXTRACCION DEL URANIO CONTENIDO EN SOLUCIONES DE ACIDOS FOSFORICOS, POR MEDIO DE UN AGENTE DE EXTRACCION CONSTITUIDO POR UN ACIDO ALCOHILPIROFOSFORICO.CONSISTE EN PONER EN CONTACTO BAJO AGITACION, LA FASE MINERAL DE ACIDO FOSFORICO Y UNA FASE ORGANICA QUE CONTIENE EL AGENTE DE EXTRACCION, PARA CREAR UNA EMULSION. LAS DOS FASES QUE CONTIENEN EL ACIDO FOSFORICO Y EL AGENTE DE EXTRACCION SE SOMETEN SIMULTANEAMENTE, DURANTE UN CIERTO TIEMPO, A UNA ACCION MECANICA DE CIZALLAMIENTO INTENSO CON EL FIN DE MULTIPLICAR LAS SUPERFICIES DE CONTACTO ENTRE ESTAS DOSFASES, Y A CONTINUACION LA EMULSION FORMADA SE ROMPE BRUTALMENTE EN UN CORTO PERIODO DE TIEMPO.
