SQM (NYSE:SQM) plans to choose one or more direct lithium extraction (DLE) technologies by next year.

The decision, confirmed by Carlos Diaz, SQM's lithium division head, at Fastmarkets' Lithium Supply and Battery Raw Materials Conference, held in Las Vegas from June 24 to 27, comes as part of a broader effort to expand production of lithium, a crucial metal for electric vehicle batteries, in the Salar de Atacama region.

"We would like to have multiple (DLE) solutions," Reuters quotes Diaz as saying. "It's difficult to choose one that is going to fit and be suitable for all kinds of different chemicals that can be in different types of brine."


Diaz further revealed that the Chilean lithium company has evaluated over 70 DLE technologies and selected 12 for pilot testing, with two of the shortlisted technologies currently being tested. SQM's goal is to increase its annual lithium production to between 280,000 and 300,000 metric tons by 2060, up from an estimated 200,000 tons in 2024.

SQM is weighing several factors in its decision-making process, such as the higher electricity consumption of DLE technologies compared to traditional evaporation ponds, and the freshwater requirements of some DLE variants.

The company is also considering how reinjecting brine post-lithium extraction could impact local aquifers.

Chile is currently the world's second largest lithium producer, trailing only Australia. The country's lithium output is largely driven by SQM and its competitor, Albemarle (NYSE:ALB). Both companies are exploring the use of DLE technologies, which have yet to be proven effective on a commercial scale without the aid of evaporation ponds.

At the end of May, SQM entered into a partnership agreement with Codelco, Chile's stated-owned copper miner, through which the two will jointly exploit lithium and other products in the Salar de Atacama.

In addition to its these advancements, SQM recently secured long-term agreements to supply lithium hydroxide to Hyundai Motor (KRX:005380) and Kia (KRX:000270), two of South Korea's leading electric vehicle manufacturers.
