CleanTech Lithium PLC achieved a significant milestone in its DLE pilot plant operations in Copiapó, Chile, with the successful production of 88m3 of concentrated eluate, equivalent to about one tonne of lithium carbonate. This accomplishment marks the completion of the first stage of production from the pilot plant.
Key Highlights:
- Lithium Recovery: The DLE adsorbent demonstrated an impressive lithium recovery rate of approximately 95% from the brine, with a total recovery (adsorption plus desorption) reaching around 88%. This high recovery rate ensures efficient extraction of lithium from the brine.
- Impurity Rejection: The DLE process exhibited exceptional impurity rejection rates, resulting in a low impurity eluate suitable for downstream conversion to battery-grade lithium carbonate. This high purity eluate stream is crucial for producing high-quality lithium products.
-
Shipment Status: The concentrated eluate is being shipped to Conductive Energy in Chicago, USA, for further processing into battery-grade lithium carbonate. The table below outlines the shipment volumes, lithium grades, and current statuses.
- A total of four batches, each with varying eluate volumes and lithium grades, are in transit or have arrived at the processing facility.
- The targeted LCE (lithium carbonate equivalent) and the actual achieved quantity demonstrate the success of the production process.
- Downstream Processing: Conductive Energy conducted test-work on a 200L concentrated eluate sample to optimize the conversion process. The results confirmed the production of battery-grade lithium carbonate with 99.75% purity, meeting industry standards.
These achievements underscore CleanTech Lithium’s position as a leader in DLE-based lithium projects in Chile. The successful production from the pilot plant will provide large test samples for potential partners seeking product qualification.
Looking ahead, the completion of the re-injection well at the Laguna Verde project is crucial for the reserve report scheduled for October 2024. CleanTech Lithium’s Executive Chairman, Steve Kesler, emphasized the significance of these results in demonstrating the company’s capability to produce battery-grade lithium efficiently.
In conclusion, CleanTech Lithium’s successful pilot plant operations and downstream processing mark a significant step towards commercial production of battery-grade lithium in Chile. The company’s commitment to sustainability and innovation positions it as a prominent player in the clean energy transition.
