Abstract: The invention relates to a lithium adsorption-desorption apparatus including a plurality of reaction tanks arranged in a row; a guide rail disposed at an upper portion of the reaction tank; a movable driving unit coupled to a moving means that moves along the guide rail; and a reaction housing which is mounted to the driving unit, and can be vertically moved or rotated in a state in which the lithium adsorbent is fixed thereto, and after immersing in the reaction tank, accelerates adsorption or desorption of lithium, and after being lifted, discharges residual solution from the lithium adsorbent by rotation movement.Therefore, the lithium adsorption desorption apparatus can fix a large amount of lithium adsorbent and immerse it in a lithium-containing solution to effectively adsorb lithium and then quickly desorb lithium in a desorption solution, and can efficiently wash the lithium adsorbent in a cleaning solution.

Abstract: The present disclosure relates to an onshore lithium-recovering device for a lithium ion adsorption and desorption process including a supply unit for supplying lithium-containing water in which lithium is dissolved, a composite unit, a washing unit, a desorbing liquid unit, an extract liquid unit, a pressure adjusting unit, a discharge unit, and a control unit. Therefore, the lithium adsorption means is moved onshore so it is possible to significantly reduce the plant installation cost and the operating cost as compared to the lithium recovery process that operates the conventional offshore plant.
