Steve Kesler, Govt Chairman and Interim CEO, of CleanTech Lithium PLC, mentioned:

“Our crew has undertaken an incredible quantity of labor on deciding on and optimising the DLE course of for the Laguna Verde mission, and this has prolonged to the downstream conversion course of the place we’re working with Conductive Power. Earlier test-work confirmed {that a} downstream course of has been developed that may effectively produce battery-grade lithium carbonate for the Laguna Verde mission at pilot scale, together with use of Ahead Osmosis which we’re investigating instead for eluate focus. This has the potential to decrease power consumption, CO₂ emissions and each capital and working prices.”

Additional Info

CleanTech Lithium has engaged Conductive Power for the conversion of lithium chloride eluate, produced utilizing feed brine from Laguna Verde at our DLE pilot plant in Copiapó, Chile, into battery-grade lithium carbonate. 4 containers of eluate with a complete quantity of 88m³ have been obtained by Conductive Power at its Chicago, USA, facility with conversion to start in October 2024. Conductive Power´s conversion course of is proven in Determine 1 which relies on normal trade course of steps, aside from the trialing of Ahead Osmosis within the eluate focus stage as a substitute for utilizing a comparatively extra power intensive thermal evaporator.

Determine 1: Conductive Power Conversion Course of

As due diligence in investigating various applied sciences able to enhancing course of efficiency, iFO was trialed in course of test-work on a 200L pattern of eluate undertaken at Conductive Power´s amenities in Q2 2024. The complete outcomes of this test-work, which produced a pattern of battery grade lithium with a purity of 99.75% lithium carbonate, was reported to the market on July 22, 2024. Outcomes of the iFO stage of the take a look at work achieved excellent efficiency supporting the alternative of a thermal evaporator in concentrating eluate, with the important thing parameters and outcomes offered in Desk 1:

Desk 1: Outcomes from focus of Laguna Verde eluate by R/O adopted by iFO

A focus of 18,000mg/L Li was set because the goal focus throughout iFO testing, consultant of a typical lithium focus used within the carbonation conversion course of. Based mostly on the Laguna Verde eluate, iFO can focus lithium as much as 50,000 mg/L Li. Whole water restoration of 94% was achieved in the course of the eluate focus, with the remaining 6% recycled or returned within the course of. The DLE adsorbent used to provide the concentrated eluate achieved very excessive impurity rejection charges, aside from boron, as beforehand reported (RNS July 22, 2024).

iFO testing was optimised for boron elimination leading to a 55% discount based mostly on weight. The achieved boron discount is critical enabling improved course of effectivity and product high quality, whereas lowering power consumption and working prices related to elimination of boron utilizing Ion Alternate (IX), which is the final course of step previous to carbonation. Within the Laguna Verde PFS presently underway, recovering this boron as a saleable by-product is being investigated.

Different advantages of iFO use embody a 60% discount in power consumption in comparison with typical thermal evaporators, and as much as 80% if operated utilizing a renewable power supply akin to photo voltaic thermal as depicted in Determine 2 beneath. iFO´s low power use when in comparison with thermal evaporation allows CO₂ emission discount by as much as 60%, underscoring the sustainability advantages of this progressive know-how.

Determine 2: Depiction of economic scale iFO plant with photo voltaic thermal energy provide

Because of iFO efficiency throughout testing, CTL requested Conductive Power to exchange the thermal evaporator with iFO in the course of the downstream conversion course of for the subsequent stage of conversion test-work, wherein further iFO working info may be obtained akin to power necessities. A iFO demonstration unit with the capability to course of 35 m³/day of concentrated eluate will likely be provided by Ahead Water Applied sciences, which is proven in Determine 3 beneath, when remaining commissioning was underway. The unit is now prepared for cargo from Toronto, Canada, and is predicted to reach on the Conductive Power facility in Chicago, USA, in roughly one week. An extra one week of on web site commissioning is deliberate earlier than the eluate conversion course of will begin.
