There are two primary methods for extracting lithium from brine: Direct Lithium Extraction (DLE) and evaporation ponds. Evaporation ponds are the more traditional method, involving the use of large, shallow ponds to evaporate the brine and concentrate the lithium salts, which can then be harvested and processed. DLE, on the other hand, involves selectively removing lithium ions from the brine using specialized materials or membranes that selectively bind with lithium ions. DLE methods are becoming increasingly popular due to their higher efficiency, lower environmental impact, and ability to extract lithium from lower-grade brines.
