Most of the world’s lithium reserves are found in salt brines, with current production concentrated in South America. The conventional process for extracting lithium from brines requires large evaporation ponds that are expensive, slow to startup, vulnerable to weather, and often impossible to permit. This conventional process suffers from low lithium recovery and is ineffective for most new brine discoveries with lower grades of lithium. Lithium producers are seeking new extraction methods.

Lilac Solutions has developed a new ion exchange technology to address the challenges faced by lithium producers. Lilac's technology cuts capital and operating costs, accelerates project startup, boosts lithium recovery, and unlocks new resources. Our process is modular and can be ramped up quickly through pilot and commercial projects.

The company’s unique ion exchange beads and continuous column system together enable a simple and robust process yielding concentrated high-purity lithium solutions from a wide variety of resources. These solutions can be fed into conventional downstream processes for production of battery-grade lithium chemicals. Our process can access brines with low concentrations of lithium while rejecting large amounts of impurities including divalent ions. Lilac founder and CEO Dave Snydacker pioneered novel materials design methodologies for lithium extraction during his PhD at Northwestern.

Lilac is a mining technology company and is building partnerships with brine developers and operators around the world.
