Abstract: The present disclosure provides a lithium extraction apparatus, which includes a frame and a transmission mesh belt. The transmission mesh belt includes water permeable holes, and is configured to carry an adsorbent. The frame includes an adsorption zone and a desorption zone along a traveling direction of the transmission mesh belt. A brine spraying device is disposed above the transmission mesh belt in adsorption zone. A desorbing liquid spraying device is disposed above the transmission mesh belt in the desorption zone, and a lithium extract collecting device is disposed below the transmission mesh belt in the desorption zone. The transmission mesh belt in the adsorption zone is folded into a multi-layer structure in the vertical direction; and/or the transmission mesh belt in the desorption zone is folded into a multi-layer structure in the vertical direction.

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.
