Abstract
SE DIVULGA UN PROCEDIMIENTO PARA LA RECUPERACIÓN DE LITIO A PARTIR DE ESCORIAS METALÚRGICAS QUE COMPRENDE LOS PASOS DE TOSTAR ESPODUMENO PARA CONVERTIRLO DE LA VARIANTE ALFA A LA BETA; HACER REACCIONAR LA VARIANTE BETA CON ÁCIDO SULFÚRICO, UTILIZANDO UN EXCESO ESTEQUIOMÉTRICO DE ÁCIDO; VOLVER A REDUCIR A PULPA EL PRODUCTO DE REACCIÓN CON AGUA, FORMANDO UNA SUSPENSIÓN ÁCIDA; NEUTRALIZAR LA SUSPENSIÓN ÁCIDA A UN PH ENTRE 5 Y 7, MEDIANTE LA ADICIÓN DE POR LO MENOS UN AGENTE NEUTRALIZANTE; FILTRAR LA SUSPENSIÓN NEUTRALIZADA, OBTENIENDO ASÍ UNA SOLUCIÓN PORTADORA DE LITIO Y UN RESIDUO; CARACTERIZADO PORQUE, EN UNO O EN AMBOS PASOS DE NUEVA REDUCCIÓN A PULPA Y NEUTRALIZACIÓN DE LA SUSPENSIÓN ÁCIDA, LA ESCORIA METALÚRGICA PORTADORA DE LITIO ES AGREGADA COMO AGENTE DE NEUTRALIZACIÓN. LA ESCORIA METALÚRGICA PORTADORA DE LITIO ES UTILIZADA PARA SUBSTITUIR POR LO MENOS PARTE DEL AGENTE NEUTRALIZANTE TÍPICO. EL LITIO EN LA ESCORIA ES LIBERADO Y AGREGADO AL LITIO LIBRE DEL ESPODUMENO.
