Albemarle’s $3.1B Chile DLE project: design and water balance notes for mine engineers

30 Second Briefing
Albemarle has begun environmental review for its $3.1 billion “Transition to Direct Lithium Extraction (TED)” project in Chile’s Atacama salt flat, aiming to integrate DLE with existing solar evaporation to nearly double lithium recovery without increasing authorised brine extraction. The plant will use up to six processing circuits with a combined capacity of 300 litres per second, cutting net extraction from 442 l/s to 342 l/s and returning about 90% of processed brine to the salar. Infrastructure includes a 29 km, 220 kV transmission line tied to Chile’s renewable grid, a 73-hectare facility footprint, and up to 450 permanent jobs through 2045.
Technical Brief
- TED capex is estimated at $3.1 billion, currently the largest lithium investment under Chilean SEIA review.
- Project life is planned through 2045, aligning DLE deployment with Albemarle’s existing Atacama operating horizon.
- Albemarle confirms no new evaporation ponds or additional surface areas are required beyond current concessions.
- The 73-hectare plant layout separates a civic centre (offices, services) from the industrial processing zone.
- A new 29 km, 220 kV transmission line will interconnect with Chile’s national, largely renewable, power grid.
- Early community engagement involved over 1,250 participants prior to formal SEIA submission, indicating high stakeholder interface.
- Construction phase employment is projected at about 350 jobs, transitioning to up to 450 permanent roles in operation.
- Company statements cite more than a decade of DLE research in Chile underpinning the TED process design.
Our Take
Albemarle’s $3.1 billion TED DLE project in Chile comes just weeks after our coverage of the company idling its Kemerton lithium hydroxide plant in Australia, suggesting a strategic pivot to lower-cost brine-based supply in the Atacama rather than near-term expansion of hard‑rock conversion capacity.
Among recent Chile items in our database, only a handful involve project lives stretching beyond 2040; TED’s useful life to 2045 positions Albemarle as a long-duration lithium anchor in the Atacama, comparable in strategic horizon to large copper expansions like Freeport-McMoRan’s proposed $7.5B El Abra upgrade.
