In the arid plains of northern Argentina’s mountains, tall black tubes fill a massive tank with salty brine extracted from deep underground. This brine is rich in lithium, a vital metal for producing electric vehicle batteries and in high demand as the world embraces green energy solutions.
French mining company Eramet is pioneering a new technique known as direct lithium extraction (DLE) to produce lithium more efficiently, quickly, and with minimal water usage. Unlike traditional methods that rely on large evaporation pools, DLE extracts lithium at a much faster rate, making it essential for global lithium production as 70% of the world’s lithium is found in brine deposits.
Eramet’s innovative approach is being closely observed by competitors worldwide, with plans to produce its first ton of lithium carbonate by November and scale up production to 24,000 metric tons annually by mid-2025.
The project, located in the province of Salta, positions Argentina as a key player in the lithium market, with upcoming projects from major mining companies like Rio Tinto, Posco, Zijin, and Ganfeng set to further boost the country’s lithium production capacity.
Eramet’s ambitious venture aims to address the challenges of lithium production by customizing the extraction process to suit specific brine deposits. While the success of their strategy remains to be seen, industry experts are optimistic about the potential of DLE technology.
The DLE process at Eramet’s Centenario plant involves a unique sorbent material that efficiently absorbs lithium from brine, yielding a higher lithium content compared to traditional methods. This allows Eramet to produce lithium carbonate in a fraction of the time required by conventional approaches.
As Eramet works towards full-scale production, its focus on water recycling and sustainability reflects the industry’s commitment to reducing environmental impact. Eramet plans to recycle a significant percentage of water used in the extraction process, aligning with global efforts to mitigate water consumption in lithium production.
Despite concerns from environmentalists about the impact on local ecosystems, Eramet aims to adhere to strict mining standards and minimize water usage and chemical usage in future projects.
Looking ahead, Eramet and its partner Tsingshan are optimistic about the potential of their technology and plan to target buyers in China and Asia. Despite market challenges, Eramet remains confident in the profitability of its operations, with current prices exceeding cash costs per ton.
