Title
(EN) PROCESS FOR SELECTIVE ADSORPTION AND RECOVERY OF LITHIUM FROM NATURAL AND SYNTHETIC BRINES
(FR) PROCÉDÉ D'ADSORPTION SÉLECTIVE ET DE RÉCUPÉRATION DE LITHIUM À PARTIR DE SAUMURES NATURELLES ET SYNTHÉTIQUES
Abstract
(EN) This invention relates generally to a process for selective adsorption and recovery of lithium from natural and synthetic brines, and more particular to a process for recovering lithium from a natural or synthetic brine solution by passing the brine solution through a lithium selective adsorbent in a continuous countercurrent adsorption and desorption circuit.
(FR) La présente invention concerne de manière générale un procédé d'adsorption sélective et de récupération de lithium à partir de saumures naturelles et synthétiques, et plus particulièrement un procédé de récupération de lithium à partir d'une solution de saumure naturelle ou synthétique par passage de la solution de saumure à travers un adsorbant sélectif au lithium dans un circuit d'adsorption et de désorption à contre-courant continu.
