DLE Lithium Extraction: A More Sustainable Approach

As the world shifts toward electrification, the demand for lithium is expected to surge over the next decade. To meet this increasing demand, a new wave of startups is pioneering Direct Lithium Extraction (DLE), an innovative method designed to unlock untapped lithium sources.

Experts argue that, despite the current oversupply of lithium, achieving long-term energy transition goals will require new and innovative sources to meet future demand. One such innovation is the DLE method, which extracts lithium from brine using advanced techniques such as lithium-attracting beads and selective membranes to isolate the metal. While DLE technology has been developed for several years, it has only recently progressed to a point where it might compete with conventional extraction methods.

Experts believe DLE could also become competitive in the lithium market due to its reduced water usage and resource efficiency. In contrast, traditional methods are water-intensive, requiring up to 500,000gal/t of lithium produced. This high level of water consumption has prompted countries like Chile to impose restrictions on water usage in lithium mining.

Despite its advantages, the economic viability of DLE remains uncertain due to the recent collapse in lithium prices that has shaken investor confidence. Additionally, producing lithium through DLE is currently more expensive than traditional methods, though it can sometimes be comparable to the costs of hard-rock mining. In addition, its success depends on continued technological advancements and cost reductions to compete effectively with established extraction methods.
