Resource Recovery and Lithium

It is complex and resource-intensive to extract lithium and other high-demand, valuable resources from brine deposits found in continental, geothermal, and oil field sources. Traditional methods have relied on inefficient solar evaporation ponds to concentrate lithium — requiring enormous areas of land and great patience given that processing times can take years. We offer an alternative solution that is advanced and highly efficient.

Gradiant’s Direct Lithium Extraction (DLE) and production is a breakthrough process that yields lithium with far greater efficiency through an integrated flowsheet that includes adsorption, ion exchange, solvent extraction, and membranes. This technology stack results in the sustainable production of battery-grade lithium compounds using our patented RO Infinity (ROI), powered by SmartOps AI – an integrated platform for performance optimization and asset management.

We offer comprehensive end-to-end solutions for DLE from extraction of lithium from brine deposits or geothermal brines, to concentrating lithium chloride solutions, and converting to battery-grade lithium carbonate or lithium hydroxide solutions.

We have proven know-how to:

Yield the high-value end-product the industry demands
Efficiently process lower ore grades
Customize solutions for complex process streams
Ensure environmental discharge compliance
Design and operate facilities in remote locations

Gradiant’s DLE solutions deliver unprecedented performance compared to conventional methods:

Higher levels of lithium concentration in a fraction of the time
Reduced water and carbon footprints
Lower capital and operational costs
Flexible design allows for integration into existing lithium extraction and production sites
Opportunity to open untapped lithium production regions previously not viable

Beyond lithium, Gradiant technologies are proven commercially in the sustainable production and recovery of other valuable metals, including nickel, cobalt, graphite, and uranium. In addition, we offer solutions for IPA recovery in the semiconductor industry.
