Lithium Extraction and Refining
Concentrate, Refine, Separate, & Crystallize
Saltworks helps to improve and accelerate lithium recovery processes: concentrating lithium brines to reduce evaporation time, separating lithium ions from contaminants, and improving recovery. Contact us to see how Saltworks can help you to cost-effectively extract lithium from your brines.

Lithium Brines
The primary sources of lithium are brines from salars and salt lakes, and as spodumene ores, while geothermal brines represent secondary sources. Chemical precipitation, adsorption with inorganic ion exchange sorbents, solvent extraction and concentration with membrane technologies are the primary means of lithium recovery from brines.
New advances in water treatment offer exciting improvements on the economics of using membrane technologies for lithium recovery. We do bench testing and deploy mobile plants so we know the water chemistry of your lithium source and how best to proceed.
Concentrate, Refine, & Separate
Our XtremeRO products can reach lithium brine concentrations that are twice those of conventional reverse osmosis systems.
One of our electrodialysis reversal (EDR) products, Flex EDR Selective, can separate lithium ions from divalent contaminating ions, to improve the purity of your brine.
BrineRefine is our precision chemical softening and simplified solids management system. It can target specific metals and ions for removal, all in a modular, compact skid. It can make your desired lithium products while avoiding large infrastructure such as clarifiers.
Crystallize & Harvest
Our SaltMaker solutions can further concentrate lithium brines, then crystalize. For example:
- SaltMaker MultiEffect can use low grade heat for efficiency, with options for selective crystallization at different temperatures
- SaltMaker AirBreather can be operated open- or closed-to-air, with built-in management of volatile organics

Lithium Brine Extraction Technologies & Approaches
Recovering lithium in evaporation ponds can take a year or more and leaves behind lots of salt waste, but there are new technologies and processes that offer exciting options for lithium extraction.
Saltworks Enters Lithium Brine Extraction with Standard Lithium
Standard Lithium has commissioned Saltworks Technologies to design and build their novel, selective crystallization pilot plant. The plant is intended to make battery-grade lithium carbonate in a continuous process using lithium brine extraction.
Introducing the AirBreather: Lower Cost Evaporator Crystallizer
A lower cost evaporator crystallizer has emerged – the SaltMaker AirBreather. It is based on the robust backbone of its closest relative – the SaltMaker MultiEffect.
Battery Grade Lithium Produced Following Successful First Pilot Test
Standard Lithium’s novel selective crystallization process is producing battery grade lithium carbonate in a pilot plant at Saltworks Technologies. The process includes Saltworks’ robotized BrineRefine water plant and our innovative process engineering.
