Abstract
En la presente divulgación se da a conocer un proceso de reciclaje de ácido, base y los reactivos de sal requeridos en el proceso de recuperación de Li. Se implementa una celda de electrólisis por membrana que incorpora un cátodo despolarizado con oxígeno (ODC) para generar los productos químicos requeridos in situ. El sistema puede utilizar una porción de la salmuera de salar u otra salmuera que contenga litio o residuos sólidos para generar ácido clorhídrico o sulfúrico, hidróxido de sodio y sales de carbonato. La generación simultánea de ácido y base permite aprovechar ambas sustancias químicas durante la recuperación convencional de Li a partir de salmueras y rocas minerales. El agua desalinizada también puede ser utilizada para las etapas de lavado en el proceso de recuperación o ser devuelta a los estanques de evaporación. El método también puede ser utilizado para la conversión directa de sales de litio en LiOH, un producto de alto valor. El método no produce ningún efluente sólido, lo que facilita su adopción para uso en las plantas industriales de recuperación de Li existentes.
