Abstract
A method for recovering lithium from a lithium-containing solution is provided. A lithium-containing solution with an adjusted pH value or an unadjusted pH value is mixed with a meta-aluminate, and the pH value is adjusted to weak acid/neutral, so that lithium can be separated from the lithium-containing solution in the form of a precipitate of LiX·2Al(OH)·nHO. Then, the precipitate is converted into a lithium adsorbent of (1-m)LiX·2Al(OH)·nHO and a LiX-containing filtrate through desorption of lithium. High-purity LiCOis obtained by performing precipitation of lithium on the LiX-containing filtrate.
