Rio Tinto, Eramet, LG Energy Pursue Lithium Extraction Tech in Chile

April 24, 2024 : A consortium of prominent multinational corporations has expressed interest in developing lithium extraction technology for Chile’s Salares Altoandinos salt flat. This initiative, currently in its early stages of exploration, involves Rio Tinto, a leading mining company, Eramet, another major mining firm, and LG Energy, a prominent battery manufacturer.

The Chilean state-run mining entity ENAMI issued a call for proposals last month, soliciting innovative techniques for extracting lithium from the brine deposits present within the Salares Altoandinos. In response, over 30 companies submitted proposals, including the consortium above.

ENAMI has outlined specific requirements for the proposed pilot tests. The bidding companies are tasked with detailing a step-by-step approach for analyzing the salt flat’s brine composition. Furthermore, they must outline viable processes for attaining battery-grade lithium and demonstrate a plan for evaluating the environmental impact of brine reinjection, a crucial aspect of sustainable lithium extraction.

This development underscores Chile’s strategic ambitions to capitalize on its rich lithium reserves. The South American nation is recognized as a world leader in lithium deposits, and the successful extraction of battery-grade lithium from the Salares Altoandinos has the potential to significantly bolster Chile’s position within the global lithium market.

The involvement of a Rio Tinto, Eramet, and LG Energy consortium signifies the project’s potential for significant advancements. Rio Tinto and Eramet bring extensive expertise in large-scale mining operations, while LG Energy’s participation injects valuable knowledge from the battery manufacturing sector. This collaborative approach could develop efficient and environmentally responsible lithium extraction technologies.

ENAMI is evaluating proposals. The selection of a successful bidder will pave the way for the commencement of pilot tests at the Salares Altoandinos, marking a crucial step toward unlocking Chile’s lithium potential.
