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
