Abstract

SE REFIERE A UN METODO PARA LA RECUPERACION SELECTIVA DE URANIO DE UNA SOLUCION DE URANIO ACUOSA ACIDA BASADA EN SULFATO QUE CONTIENE HIERRO Y OTROS METALES POR MEDIO DE EXTRACCION CON SOLVENTE, EN EL QUE EL EXTRACTANTE USADO EN LA SOLUCION DE EXTRACCION ORGANICA ES BIS (2-ETILEXIL) FOSFATO Y UN OXIDO DE TRIALQUIL FOSFINA LIQUIDO Y RAMIFICADO ES EL AGENTE DE MODIFICACION. LA CONCENTRACION DE URANIO EN LA SOLUCION DE ALIMENTACION ES MENOS DE 50 mg/L Y UN AGENTE DE REDUCCION SE INTRODUCE EN LA SOLUCION ACUOSA Y/O DE EXTRACCION PARA PREVENIR LA OXIDACION PERMANENTE DE HIERRO A TRIVALENTE. EN EL METODO LA MAYOR PARTE DE LA SOLUCION DE EXTRACCION SE HACE CIRCULAR EN UN CIRCUITO QUE CONSISTE DE LA ETAPA DE EXTRACCION Y EL TANQUE DE ALMACENAMIENTO Y SOLAMENTE UNA PEQUENA PARTE DE LA SOLUCION DE EXTRACCION CARGADA DE URANIO ES DIRIGIDA A LA DEPURACION Y EXTRACCION
