The installation of a commercial-scale Direct Lithium Extraction (DLE) column by Standard Lithium represents a significant stride in the lithium extraction industry. From a chemical engineering perspective, the transition from demonstration to commercial-scale operations is non-trivial. It involves a scale-up of technology that must maintain efficiency, safety and cost-effectiveness. The reported 95.9% lithium recovery rate is notably high, suggesting an efficient extraction process. However, maintaining this efficiency at a commercial scale will be a critical factor in determining the project's viability. The rejection of over 99.3% of key contaminants indicates a high purity of the lithium chloride solution produced, which is crucial for battery-grade lithium production.
Furthermore, the negligible degradation of the sorbent media and the optimization of brine pre-treatment are essential for the longevity and sustainability of the operation. These factors directly influence operational costs and the environmental footprint of the extraction process. The chemical engineering challenges in scaling up such a process include ensuring consistent material properties and process dynamics, which can significantly alter the outcome when moving from a smaller scale operation to full commercial deployment.
From a market research perspective, Standard Lithium's advancement in DLE technology is timely, given the increasing demand for lithium for electric vehicle (EV) batteries and energy storage solutions. Achieving a commercial-scale operation could position the company as a key player in the North American lithium market, which is currently underdeveloped compared to other regions like South America and Australia. The ability to process large volumes of brine and achieve high lithium recovery rates could give Standard Lithium a competitive advantage in cost and sustainability, factors increasingly important to investors and consumers alike.
Moreover, the company's focus on derisking the technology through extensive testing and optimization could enhance investor confidence and potentially impact the stock's performance positively. The partnership with Koch Technology Solutions and the continuous operation of the Demo Plant for over four years provide a solid foundation for the reliability and scalability of the technology. The market will closely watch the commissioning and subsequent performance data to assess the commercial viability and potential market impact of this technology.
Analyzing the financial implications of Standard Lithium's latest development, the successful scale-up of DLE technology could have substantial effects on the company's financials. With the lithium market projected to grow significantly due to the EV revolution, the company's ability to produce lithium at high recovery rates and low contaminant levels could translate into lower production costs and higher margins. The long-term financial benefits also hinge on the technology's operational reliability and the potential to reduce environmental and regulatory risks associated with lithium extraction.
Investors should note that the capital expenditure required to establish commercial-scale operations can be substantial and the company's ability to manage these costs will be critical. The data from the commercial-scale unit will be vital for project finance processes, providing a clearer picture of the expected return on investment. Additionally, the ongoing FEED and DFS studies will offer more detailed insights into the project's capital and operational cost structures, which are essential for a comprehensive financial analysis.

Further Derisks DLE Process With Testing Planned Using Full-Scale Commercial Equipment Over the Next 6 Months
EL DORADO, Ark., March 13, 2024 (GLOBE NEWSWIRE) -- Standard Lithium Ltd. (“Standard Lithium” or the “Company”) (TSXV:SLI) (NYSE American:SLI) (FRA:S5L), a leading near-commercial lithium development company, is pleased to announce that it has successfully installed a commercial-scale Direct Lithium Extraction (“DLE”) column at its Demonstration Plant near El Dorado, Arkansas. The column is a LiPRO™ Lithium Selective Sorption (“LSS”) unit, supplied by Koch Technology Solutions, LLC (“KTS”).
The column has been installed and integrated with the Company’s existing Demonstration Plant to test and derisk the design for commercial applications of the LiPRO™ LSS technology. It is the same size and design as those that the Company intends to use (in multiple trains) in its commercial applications for the Phase 1A and South West Arkansas projects (as described in the Company’s recent Definitive Feasibility Study for the Phase 1A project and Preliminary Feasibility Study for the South West Arkansas project).
The commercial-scale LiPRO™ LSS column is currently being filled with Koch Engineered Solutions proprietary lithium-selective sorption with commissioning expected later this month. Extensive performance testing of the commercial-scale DLE technology will be performed over the following months under the supervision of Standard Lithium and KTS technical specialists.
Standard Lithium’s Director, President & COO, Dr. Andy Robinson commented, “this is an important derisking milestone for Standard Lithium and our partners. Our team has been successfully running the LiPRO™ LSS technology since October 2022, and we have already successfully completed scale-ups of the DLE equipment at the Demonstration Plant; this is our final stage of derisking the technology. The data gathered from this commercial-scale unit will provide crucial validation and derisking information for our ongoing project finance processes, as well as FEED and DFS studies for the South West Arkansas Project (see news release dated 24 January 2024 ). We’re very grateful for our partners Koch Technology Solutions and LANXESS who have helped to make this final derisking step possible .”
Standard Lithium's Demonstration Plant is the only large-scale, continuously operating DLE plant in North America. Initially commissioned in May 2020, the Plant has processed over 16.4 million gallons (62 million litres) of Smackover brine.
“The long-term operation of our Demo Plant has been crucial in replicating and understanding the real-world dynamic conditions of continuous commercial-scale operations,” said Dr. Robinson. “With our partner Koch Technology Solutions, we have been able to tailor and optimise the multi-step flowsheet that will allow the Plant to be scaled for commercial production. The knowledge we have on-hand from over four years of operations, combined with an optimised flowsheet and now a commercial-scale DLE column, puts us in a strong position as we continue to advance our projects.”
Recent technical highlights of the Demo Plant and the existing LiPRO™ LSS (DLE) column are provided below.
Key Findings:
Lithium Recovery Efficiency: As a recent weekly snapshot demonstrates (early March 2024), the LiPRO™ LSS (DLE) process achieved an average weekly lithium recovery of 95.9% from the continuous incoming brine flow. Element Rejection Rate: During the same period, the DLE process rejected, on average, over 99.3% of the key contaminants sodium, calcium, magnesium and potassium from the brine (i.e. less than 0.7% of those contaminants made it through the DLE into the first lithium chloride solution); and over 94.2% of boron was rejected. Operational Cycles: The LiPRO™ LSS (DLE) process has completed over 8,585 operational cycles. The LiPRO™ LSS column has been operating with negligible degradation or loss of the sorbent media, and brine pre-treatment has been optimized to allow for foulant-free operation of the DLE step. Brine Processed: As of the end of December 2023 (per Arkansas Oil and Gas Commission reporting), the Demo Plant had processed 16,418,408 gallons (62,143,674 litres) of Smackover brine, produced directly from the formation and reinjected continuously back into the same formation. Dr. Robinson added: “One of the fundamental findings of the Demonstration Plant is the necessity of long-duration, on-site continuous processing of real brine. Our Demo Plant handles real Smackover brine directly from the resource, whereas in traditional small-scale, short-term off-site batch processes, brine is isolated, transported and often undergoes physical and chemical changes before testing. With the commercial-scale LSS column, we can continuously test real brine from the Smackover at a commercial level.”
