Zusammenfassung:A method for extracting lithium from salt lake includes the following steps. The salt lake brine is flowed through a lithium adsorbent at a varying rate, to allow the lithium ions in the salt lake brine to be adsorbed on the lithium adsorbent, to obtain a lithium-rich adsorbent. During the adsorption process, the flow rate of the salt lake brine gradually decreases, and the difference between the initial flow rate and the final flow rate of the salt lake brine is 0.5-3BV/h. The lithium-rich adsorbent is washed. The lithium ions are desorbed from the washed lithium-rich adsorbent with a lithium ion eluent, to obtain a desorption solution.
