    Abstract: The present disclosure provides a method for separating iron element in brine. A pH adjusting agent is added to brine, to adjust the brine to pH between 6.0 and 7.0, and the temperature of the brine is controlled to between 75°C and 90°C. An oxygen-containing gas is introduced into the brine, to covert the iron element in the brine into magnetic iron oxide. The magnetic iron oxide is separated from the brine by magnetic adsorption, to obtain an iron-removed brine. The brine includes geothermal brine.

    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 solution, 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 LiaX·2Al(OH)3·nH2O. Then, the precipitate is converted into a lithium adsorbent of (1-m)LiaX·2Al(OH)3·nH2O and a LiaX-containing filtrate through desorption of lithium. High-purity Li2CO3 is obtained by performing lithium precipitation on the LiaX-containing filtrate.
