Abstract

PROCEDIMIENTO PARA LA OBTENCION DE URANIO. CONSISTE EN PONER EN CONTACTO EL ACIDO FOSFORICO QUE CONTIENE EL URANIO, EN PRESENCIA DE IONES DE HIERRO II, CON UN COMPUESTO DE ALQUILOAMINO-POLIFOSFATO Y/O ALQUILAMINO-METAFOSFATO, DISUELTO EN UN COMPUESTO ORGANICO, CONTENIENDO LA ALQUILOAMINA EN EL RESIDUO ALQUILO 8 A 30 ATOMOS DE CARBONO. EL RESIDUO DE POLIFOSTATO Y/O METAFOSFATO TIENE DE 2 A 10000 ATOMOS DE FOSFORO POR MOLECULA, PUDIENDO TENER FORMA RECTICATENARIA Y/O DE CADENA RETICULADA, RESPECTIVAMENTE CICLICA. EL URANIO PASA DE LA FASE ACUOSA A LA ORGANICA, DE LA CUAL SE EXTRAE, DE FORMA CONOCIDA. AL ACIDO FOSFORICO EN QUE ESTA CONTENIDO EL URANIO SE LE AÑADEN PRODUCTOS REDUCTORES QUE PASAN EL FE (III) A FE (II
