Abstract

METODO DE SEPARACION DE IMPUREZAS ORGANICAS, DEL TIPO DE HUMATOS, DE DISOLUCIONES Y SUSPENSIONES DEL PROCEDIMIENTO DE BAYER. CONSISTE EN INTRODUCIR EN LA DISOLUCION O SUSPENSION CON IMPUREZAS UNA SAL DE AMONIO CUATERNARIO, POLIMERA, SOLUBLE EN AGUA, QUE CONTIENE EL CLORURO DE DIALILDIMETILAMONIO MONOMERO, DE FORMULA (I), PARA REVESTIR LOS SOLIDOS DISPERSADOS; MANTENER LOS SOLIDOS REVESTIDOS EN LA DISOLUCION PARA PERMITIR LA FORMACION DE ADUCTOS CON LAS IMPUREZAS DE HUMATOS; Y SEPARAR DICHOS ADUCTOS DE LA DISOLUCION. TIENE APLICACIONES PARA LA PURIFICACION DE LAS DISOLUCIONES Y SUSPENSIONES FORMADAS EN EL PROCESO DE OBTENCION DE ALUMINIO.
