Se describe un metodo para recuperar litio de una fuente acuosa. El litio se extrae de la fuente acuosa utilizando un proceso de sorcion/desorcion para formar un extracto de litio. Se eliminan impurezas del extracto de litio para formar un extracto de litio purificado y el extracto de litio purificado se concentra utilizando un proceso de eliminacion de agua, para formar un concentrado de litio. El concentrado de litio luego se convierte en uno o mas de carbonato de litio e hidroxido de litio para formar una corriente convertida. Varias corrientes, incluidas algunas corrientes que contienen litio, se reciclan para el proceso de sorcion/desorcion. A method of recovering lithium from an aqueous source is described. Lithium is extracted from the aqueous source using a sorption/desorption process to form a lithium extract. Impurities are removed from the lithium extract to form a purified lithium extract, and the purified lithium extract is concentrated using a water removal process to form a lithium concentrate. The lithium concentrate is then converted to one or more of lithium carbonate and lithium hydroxide to form a converted stream. Various streams, including some lithium-containing streams, are recycled to the sorption/desorption process.
