Abstract
The present disclosure provides a method for extracting lithium from salt lake brine, which includes: flowing the salt lake brine through a lithium adsorbent at a varying flow rate to obtain a lithium-rich adsorbent, where the lithium ions in the salt lake brine are adsorbed on the lithium adsorbent, and where during the adsorption process, the flow rate of the salt lake brine decreases, and a difference between the initial flow rate and the final flow rate of the salt lake brine is 0.5-3 BV/h; washing the lithium-rich adsorbent; and desorbing the lithium ions from the washed lithium-rich adsorbent with a lithium ion eluent, to obtain a desorption solution.
