Standard Lithium validates performance of largest operating DLE in North America

Standard Lithium announced that it has successfully commissioned and validated the performance of the largest continuously-operating Direct Lithium Extraction, or DLE, equipment in North America. The Company recently installed a commercial-scale DLE column at its Demonstration Plant near El Dorado, Arkansas. The column is a Li-ProTM Lithium Selective Sorption, or LSS, unit, supplied by Koch Technology Solutions, or KTS. The column was installed and integrated into the Company’s existing Demonstration Plant, and is currently extracting lithium from Smackover Formation brine at an input flow rate of 90 gallons per minute. This is, to the best of the Company’s knowledge, both the largest DLE installation, and the only example of a commercial-scale DLE column in operation in North America. The performance of this commercial-scale DLE column is being used to validate the design assumptions for the Phase 1A Project and also underpins the process design work underway for the South West Arkansas Project.
