Abstract[English]
The present invention relates to a method for extracting lithium by adsorption implementing a plurality of consecutive adsorption/desorption steps and using a plurality of extraction columns (C1-C4) arranged/operated in series for an adsorption phase (a) and wherein a plurality of extraction columns (C1-C4) are arranged/operated in series for a desorption phase (b), the position/operation of the extraction columns (C1-C4) being offset by an equivalent/value of one extraction column (C1-C4) from one step i to another step i+1.[French]
La présente invention concerne un procédé d'extraction par adsorption de lithium mettant en œuvre une pluralité d'étapes d'adsorption/désorption consécutives et utilisant une pluralité de colonnes d'extraction (C1-C4) disposées/opérées en série pour une phase d'adsorption (a) et une pluralité de colonnes d'extraction (C1-C4) sont disposées/opérées en série pour une phase de désorption (b), la position/l'opération des colonnes d'extraction (C1-C4) étant décalée par un(e) équivalent/valeur d'une colonne d'extraction (C1-C4) d'une étape i à une autre étape i+1.
