The disclosed process relates to a process for selectively purifying a lithium product stream from an aqueous lithium salt-containing solution in a continuous mode, said process comprising the steps of: a) introducing said aqueous lithium salt-containing solution to an arrangement of three or more packed-bed columns in series each filled with a lithium selective sorbent, wherein at least two of said three or more columns are at an adsorption stage, with one at a leading lithium chloride adsorption stage and one or more at a trailing lithium chloride adsorption stage, and at least one of said three or more columns is simultaneously at a lithium chloride desorption stage; b) flowing said aqueous lithium salt-containing solution through said at least two of said three or more columns at a leading lithium chloride adsorption stage and a trailing lithium chloride adsorption stage to adsorb lithium chloride from the aqueous lithium salt-containing solution and respectively form a fully-saturated sorbent and a partially-saturated sorbent; c) flowing a desorbent fluid through said at least one of said three or more columns at a lithium chloride desorption stage to desorb lithium chloride from the fully-saturated sorbent in a column from a leading lithium chloride adsorption stage of a previous cycle in an eluate stream; and d) recovering a lithium product stream from the eluate stream, wherein when the lithium selective sorbent in said column at a leading lithium chloride adsorption stage is fully-saturated with lithium chloride, said column transitions directly to said lithium chloride desorption stage to desorb lithium chloride once appropriate void volume is displaced; said column at a trailing lithium chloride adsorption stage transitions directly to said leading lithium chloride adsorption stage for further adsorption of lithium chloride; and said column at a lithium chloride desorption stage transitions directly to said trailing lithium chloride adsorption stage for initial adsorption of lithium chloride once appropriate void volume is displaced; without any intermediate washing stages of the media between any of said transitions.

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.
