Most of the metallurgical testing completed to date has focused on selectively recovering lithium from brines using Direct Lithium Extraction Technologies (“DLE”), an alternative to the conventional evaporation process. DLE has the potential to shorten lithium extraction time and provide higher recovery of lithium, addressing the critical supply constraints and sustainability requirements to meet the surge in lithium demand due to the increased pace of adoption of electric vehicles and renewable energy.
• A baseline evaporation investigation is currently underway at Norlab´s facility in Salinas Grandes, Jujuy under the direction of Dr.
• Test work is underway for Direct Lithium Extraction (DLE) – a technology that can reduce production time, increase recovery rates, eliminate large evaporation ponds, and reduce the environmental footprint. Brine was delivered to Chengxin’s DLE facility in
The following are key outcomes of the DLE testing:
MINERÍA POSITIVA SRL (MP+):
MP+ conducted bench test on Selective Adsorption of Lithium using alumina-based adsorbent from a local producer. These tests include advanced chemical studies in the laboratory recently established in the province of Jujuy.
The results show that the resin recovery factor averaged 5.6 mg Li/g of resin at a flow rate of 3 BV/h at 20°C. A maximum lithium recovery of 95% was achieved during adsorption, followed by a 76.4% elution of the recovered lithium in the elution output stream. The operational product according to the analyses has an average lithium concentration in the eluate (937 mg/L) greater than three times the concentration of the lithium concentration from that of the feed brine and a lower concentration of impurities.
MP+ has made great progress on processing raw brine with Aluminum resin, currently testing pre-concentrated brine and performing additional tests to confirm results. Optimization of the DLE process and lithium conversion processes are being reviewed focusing the efforts on important operational variables such as water and energy consumption.
SUMMIT NANOTECH:
The Company delivered brine to Summit Nanotech (“Summit”) to assess the suitability of Summit’s denaLiTM technology for extracting lithium from a sample of Arizaro field brine and converting it to a high-purity lithium carbonate product. Summit’s process, which is currently being piloted in
This preliminary testing of Lithium Chile’s brine asset consistently averaged 98% adsorption yield and 98% reduction in impurities, resulting in a total recovery of 83.8% lithium. A final lithium carbonate product with a purity of 97.9% was generated without bicarbonation.
SUNRESIN NEW MATERIALS CO., LTD.:
200 Liters of bulk sample from the Arizaro project has been successfully processed through Sunresin´s proprietary DLE technology. Using Sunresin lithium adsorbent, in combination with the corresponding continuous bed technology, the adsorption performance and adsorption amount of sorbent are stable. The average value of lithium-ion content in the stable and qualified liquid is 613.28 mg/L and the lithium-ion adsorption yield of the brine is over 90%.
Single column tests and continuous system tests were performed. It aimed to verify the adsorption and desorption effect of lithium ions used in Arizaro´s brine, as well as the stability of multi-cycle tests, investigate the feasibility of industrialization and provide data support for industrialization design.
