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 vulnerable to weather, large quantities of chemical inputs, and long periods of time for construction and processing. This conventional process also suffers from low lithium recovery and cannot access new lithium resources in the US and around the world. Lithium producers are seeking new extraction methods.
Lilac Solutions has developed a new ion exchange technology to address the challenges face by lithium producers. Lilac's technology streamlines operations, boosts lithium recovery, and expands production into new resources. Our process is modular and can be ramped in time with the market.
Ion exchange depends on materials that can selectively absorb lithium from a brine and then release the lithium at a high concentration. Competing absorbents require large amounts of water, yield lithium at low concentration, and cannot access new lithium resources containing divalent ions such as calcium and magnesium. Lilac's unique ion exchange materials and beads enable a one-step process yielding concentrated high-purity lithium solutions from a wide variety of resources. Our process can access brines with low concentrations of lithium while rejecting large amounts of impurities including divalent ions.
Lilac is a mining technology company and is building partnerships with brine developers and operators around the world.
