Abstract

METODO DE ELIMINAR IMPUREZAS DE FOSFORO DE LA TORTA AMARILLA DE URANIO. LA TORTA AMARILLA SE DISUELVE EN ACIDOS SULFURICO Y CLORHIDRICO CONCENTRADOS PARA OBTENER UNA SOLUCION DE URANILO DE PH2 Y UNA CONCENTRACION DE U2O8, DETERMINADA POR ANALISIS, DE 100 A 200 G/L; SE AÑADE SUFICIENTE CANTIDAD DE PEROXIDO DE HIDROGENO PARA PRECIPITAR PEROXIDO DE URANIO Y DEJAR LAS IMPUREZAS DE FOSFATO SUSTANCIALMENTE DISUELTAS MIENTRAS SE MANTIENE EL PH DE LA MEZCLA DE REACCION DE 2,2 A 2,6; SE MANTIENEN LOS REACCIONANTES EN CONTACTO HASTA QUE SE COMPLETA ESENCIALMENTE LA PRECIPITACION DEL URANIO; Y SE RECUPERA EL PEROXIDO DE URANIO DE LAS IMPUREZAS DE FOSFATO DISUELTAS. EL METODO ES APLICABLE AL BENEFICIO DEL URANIO.
