Extraction of Lithium from Salt Lake Brine segmentation by type distinguishes four principal technologies: direct evaporation, solvent extraction, ion‑exchange, and membrane separation. Direct evaporation, the legacy method, relies on solar‑driven concentration of brine, accounting for roughly 45 % of installed capacity due to its low capital intensity but high water‑usage. Solvent extraction employs organic carriers to selectively bind lithium ions, contributing about 25 % of recent capacity expansions; its advantage lies in reduced processing time and lower impurity carry‑over. Ion‑exchange systems, typically based on resin columns, represent 20 % of the market and are favored in regions with limited land for evaporation ponds, offering modular scalability. Membrane separation, encompassing nanofiltration and electrodialysis, holds the remaining 10 % and is gaining traction for its ability to achieve high lithium recovery rates with minimal environmental footprint. Each subtype influences overall market size by dictating capital expenditure, operating costs, and geographic deployment, thereby shaping the total addressable volume of the extraction market.
