摘要： A process for recovering lithium from sea water in which sea water is repeatedly concentrated at specific gravities between 1.13 and 1.24 to thereby separate salts including common salt from the concentrate, removing the salts which separate from the concentrate, diluting the final concentrate so obtained with water, subjecting the diluted concentrate containing lithium and magnesium to a resin exchange treatment in which lithium and magnesium are absorbed on the resin, and treating the resin with an aqueous hydrochloric acid solution to elute lithium from said resin.
