Albemarle DLE Project Targets Higher Lithium Recovery in Chile’s Atacama

Albemarle

Albemarle DLE project plans in Chile could reshape lithium production at the Atacama salt flats by increasing recovery while reducing net brine extraction. The US-based lithium producer has submitted an environmental assessment for a $3.1 billion direct lithium extraction project at its Chilean operations.

The project is designed to add DLE capacity alongside Albemarle’s existing evaporation pond system. The company said the technology could recover nearly twice as much lithium while extracting up to 300 fewer liters per second of brine compared with traditional evaporation methods.

Albemarle DLE project development matters because Chile remains one of the world’s most important lithium supply regions. Any improvement in recovery, water management, and environmental performance could influence future lithium investment across brine-based operations.

Direct Lithium Extraction Could Change Atacama Production Economics

Direct lithium extraction uses chemical processing rather than long evaporation cycles. This can reduce production time from 12-18 months to just days, improving project flexibility and potentially accelerating lithium output.

Albemarle plans to install six DLE processing trains across three modules. These trains will complement the company’s evaporation ponds rather than immediately replace the existing system.

The process will produce lithium-depleted brine, which Albemarle plans to reinject into the salt flats’ reservoirs. Each DLE module would allow reinjection of 100 liters per second of brine, potentially reducing the company’s net extraction rate from 442 liters per second to 142 liters per second once the system reaches full capacity.

Infrastructure Investment Shows Scale of Lithium Transition

The Albemarle DLE project is not only a processing upgrade. The $3.1 billion plan also includes supporting infrastructure such as a power transmission line, a new electric substation, expansion of an existing substation, and adaptations to storage sites and pond systems.

Construction is expected to begin in the second half of 2028. The full buildout may take up to nine years, with modules commissioned and ramped up as they are completed.

The long timeline shows that DLE remains a complex industrial transition, not a simple plug-in technology. However, if successful, Albemarle’s project could strengthen Chile’s lithium competitiveness while responding to environmental pressure over brine extraction in the Atacama.

The Metalnomist Commentary

Albemarle’s DLE plan shows that the next phase of lithium competition will focus on recovery efficiency and environmental performance, not only reserve size. Chile’s challenge will be proving that higher output and lower brine impact can move together at commercial scale.
