The majority of the world’s battery-grade lithium is produced by one of two means:
A third method is gaining popularity, particularly in North America and China:
Lithium processing plants are water plants, refining a high grade lithium output and clean water that can be returned and re-used. Generally, the steps include concentrating a brine, chemical conversion steps to change the lithium form, washing, and final crystallization. Saltworks offers solutions for every step, including your complete package.
Our IonSelect product family removes potentially troublesome ions such as silica, thereby enabling higher recovery processing in membrane systems, reducing cost and energy associated with evaporators.
Our next generation reverse osmosis (RO) system, XtremeRO, concentrates lithium chloride (LiCl) up to 50% higher than conventional RO. These ultra high pressure (1,800 psi) reverse osmosis (UHP-RO) systems reduce downstream evaporator size and cost, and in some cases remove their need entirely.
Direct lithium extraction (DLE) operators generally extract lithium using methods unique to each site—most produce a lithium chloride solution of 1,000 to 2,000 mg/L containing impurities. We add value for clients downstream of DLE, where we can help by concentrating lithium chloride solutions and converting to battery-grade solids.
Saltworks adds value downstream of customer-selected DLE processes. We offer comprehensive modeling, piloting, and full-scale solutions that convert DLE outputs into battery grade inputs.
To ensure the highest lithium quality and yield, we precisely target impurities and selectively precipitate the lithium forms most valuable to your project. We pair smart chemical conversion processes (BrineRefine) with robust ceramic ultrafiltration (XtremeUF) to enable precise, automated, pre-packaged chemical processing technology that completes various lithium conversion steps with less chemical waste and greater precision.
Our SaltMaker evaporator crystallizers concentrate lithium brines and crystallize battery-grade lithium from solution. Built-in self-cleaning ensures reliability at optimal capacity, while producing a high purity lithium solid product.
ScaleSense offers real-time measurement of specific ions, such as calcium, enabling improved process control that boosts both yield and purity.
With Saltworks’ focus on improved purity and yields, customers save both capital and operating cost. We also reduce the need for—and size of—evaporation steps, which saves valuable energy as well as capital.

Saltworks’ water mining expertise and advanced desalination technologies are proving to be a perfect fit for lithium clients. We are delighted to announce a hat-trick of lithium wins.
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.
This free infographic brochure shows how membrane, thermal, and chemical water technologies fit into various stages of lithium production. Learn how to process lithium to battery-grade, downstream of direct lithium extraction.
Saltworks is pleased to announce the production of battery-grade lithium hydroxide from an industrial wastewater. Saltworks’ process harvests lithium hydroxide solids that reach or exceed battery-grade specifications.
