Abstract

En esta divulgación, se introduce un proceso de reciclado de ácido, base y los reactivos de sal requeridos en el proceso de recuperación de Li. Se implementa una celda electrolítica de membrana que incorpora un cátodo de oxígeno despolarizado para generar los productos químicos requeridos en el sitio. El sistema puede utilizar una porción de la salmuera de salares u otra salmuera o residuo sólido que contiene litio para generar ácido clorhídrico o sulfúrico, hidróxido de sodio y sales de carbonato. La generación simultánea de ácido y base permite tomar ventaja de ambos productos químicos durante la recuperación convencional de Li de salmueras y rocas minerales. El agua desalinizada también se puede usar en los pasos de lavado en el proceso de recuperación o regresar a los estanques de evaporación. El método también se puede usar para la conversión directa de sales de litio en el producto LiOH con alto valor. El método no produce ningún efluente sólido lo cual lo torna de fácil adopción para su uso en las plantas industriales de recuperación de Li existentes.In this disclosure, a process for recycling the acid, base, and salt reagents required in the Li recovery process is introduced. A membrane electrolytic cell incorporating a depolarized oxygen cathode is implemented to generate the required chemicals on-site. The system can utilize a portion of the salt flat brine or other lithium-containing brine or solid residue to generate hydrochloric or sulfuric acid, sodium hydroxide, and carbonate salts. The simultaneous generation of acid and base allows both chemicals to be utilized during conventional Li recovery from brines and mineral rocks. The desalinated water can also be used in washing steps in the recovery process or returned to evaporation ponds. The method can also be used for the direct conversion of lithium salts to the high-value LiOH product. The method produces no solid effluent, making it easily adoptable for use in existing industrial Li recovery plants.
