Abstract

PROCEDIMIENTO PARA LA PURIFICACION DE AL MENOS UNA FRACCION DEL LIQUIDO PROCEDENTE DE LA OBTENCION DE ALUMINA DESTINADA A SER TRANSFORMADA EN ALUMINIO, SEGUN EL CICLO BAYER. CARACTERIZADO PORQUE EL AGENTE DE DESESTABILIZACION DEL ESTADO DE SOBRESATURACION INTRODUCIDO EN EL LIQUIDO BAYER, PARA PROVOCAR LA PRECIPITACION DEL OXALATO DE SODIO, SE ELIGE DENTRO DEL GRUPO QUE COMPRENDE OXALATO DE CALCIO Y OXALATO DE BARIO; Y PORQUE, EN EL CASO DE LIQUIDOS CARGADOS CON MATERIAS ORGANICAS DEGRADADAS, PROCEDENTES DEL ATAQUE A TEMPERATURA ALTA DE BAUXITAS RICAS EN MATERIAS HUMEDAS, SE INTRODUCE PREVIAMENTE EN DICHOS LIQUIDOS UN POLIELECTROLITO ANIONICO DE SINTESIS, SELECCIONADO ENTRE POLI(ACIDOS ACRILICOS), POLIACRILAMIDAS Y POLIACRILAMIDA.
