A mine in northern Chile has doubled its lithium extraction rate since installing Atlas Copco’s WEDA drainage pumps. Operators at the South American mine wanted to improve their lithium extraction process and turned to Atlas Copco’s distribution partner, TRILE, for expert advice and a reliable solution. In addition to optimising its process, the mine has also reduced its maintenance costs by 60%. 

The importance of lithium

Lithium is crucial to global decarbonization and the energy transition. It is an essential component for batteries, such as those found in electric vehicles and energy storage systems. Demand for lithium is at an all-time high, with global demand expected to double between 2025 and 2030 to surpass 2.4 million metric tons. By 2035, demand is expected to reach 3.8 million tons.

In 2023, Chile accounted for roughly 24% of global lithium production, estimated at 44,000 metric tons. This is a more than 15% year-on-year increase.

WEDA submersible pumps being installed for lithium extraction

The Chilean mine was achieving brine depths of 25cm in its ponds using existing dewatering pumps but wanted to reduce this level to improve operational efficiencies and optimise its lithium extraction process. Those responsible of the mine approached Atlas’s Copco’s regional distribution partner, TRILE, to find the most suitable solution.

We worked closely with our mining client to fully understand their requirements. Product reliability in reaching low brine levels was key. We have vast experience with Atlas Copco‘s submersible drainage pumps and were able to design an optimal solution based on the WEDA D line for this application.
