Schlumberger has entered into a partnership with Gradiant, a global water solutions provider, to introduce a key sustainable technology into the production process for battery-grade lithium compounds.
As part of Schlumberger’s NeoLith Energy direct lithium extraction (DLE) and production flowsheet, Gradiant technology is used to concentrate the lithium solution and generate fresh water—a critical element in sustainable lithium production from brine.
Gradiant’s new solution enhances the impact of the sustainable lithium extraction process—reduced time-to-market and environmental footprint. The technology enables high levels of lithium concentration in a fraction of the time required by conventional methods, while also reducing carbon emissions, energy consumption, and capital costs when compared to thermal-based technologies. This technology integration can be applied into new lithium mineral extraction and production sites, opening opportunities to untapped lithium production regions, as well as existing lithium production operations.
The collaboration will enable the lithium industry to meet surging mineral demand with a previously unattainable level of water utilization, by simultaneously lowering the consumption of fresh water and reducing wastewater.
Gradiant is a global solutions provider for advanced water and wastewater treatment with headquarters in Boston, Massachusetts, and Singapore.
