Abstract

METODO DE CONCENTRACION DE UN MATERIAL QUE CONTIENE URANIO Y CALCIO EN SOLUCION. LA SOLUCION LIXIVIANTE RICA EN URANIO ENTRA POR LA CONDUCCION (10). OPCIONALMENTE SE PUEDE INTRODUCIR TAL CORRIENTE POR EL CONDUCTO (11) PARA SER INTRODUCIDO EN LA MEMBRANA SEMIPERMEABLE (13) DONDE SE ELEVA EL PH DEL LIXIVIANTE HASTA 9 O 10, DE FORMA QUE SE PRECIPITA EL CALCIO EN FORMA DE CARBONATO, SALIENDO POR LA LINEA (14) LA PASTA DE CALCITA Y RETORNANDO EL LIXIVIANTE RICO EN URANIO A LA CORRIENTE PRINCIPAL POR LA LINEA (15). OPCIONALMENTE SE PUEDE BAJAR EL PH CON GAS CO2 A PARTIR DE LA LINEA (17) Y TAMBIEN SE PUEDE AÑADIR POR LA LINEA (18) ACIDO CITRICO O CUALQUIER OTRO AGENTE FORMADOR DE COMPLEJO CON EL URANIO. POSTERIORMENTE PASA A LA MEMBRANA SEMIPERMEABLE (16) DE GRAN FLUJO, TIPO ENROLLADA EN ESPIRAL, SALIENDO YA POR EL CONDUCTO (17) EL URANIO POR EL CONDUCTO (18) Y EL LIXIVIANTE DESPROVISTO DE URANIO, PUDIENDO OPCIONALMENTE UTILIZARSE EL SISTEMA DE PURIFICACION (20) PARA CONCENTRAR Y ELIMINAR UNA CANTIDAD DE LOS ANIONES, CATIONES Y OTRAS IMPUREZAS QUE SALEN POR EL CONDUCTO (18).
