The apparatus for recovering Lithium comprises: a supply unit (1) in which lithium-containing water is passed through a filter membrane to yield lithium solution; an adsorption unit (2) in which said solution adsorb the lithium in a column; an elution unit (3) by which hydrochloric acid elute the lithium in the column, yielding a lithium elute containing hydrochloric acid and lithium chloride; a cleaning unit (4) by which the column is washing; a condensing unit (5) in which the lithium elute is circularly vaporized, and the vapor is condensed to yield concentrated lithium chloride solution; a collecting unit (6) in which sodium carbonate is added to lithium chloride solution to collect the lithium as concentrated lithium solution; and a hydrochloric acid recycling unit (7) in which the residue from lithium chloride solution is cooled to yield the hydrochloric acid as used in the elution unit (3).
