Where Does Lithium Come From?

Where does lithium come from?

Key Takeaways

  • Lithium comes from two main sources: hard rock mines and underground brine deposits.
  • Australia leads global production; Chile and Bolivia hold the world’s largest known reserves.
  • The U.S. imports over 90% of its lithium, with just one active mine currently operating.
  • ÐÓ°ÉPro’s ³Ò·¡°Õ-³¢¾±³Ùâ„¢ platform is producing domestic lithium from U.S. brine today.

Lithium comes from two primary geological sources: hard rock ore deposits, found chiefly in Australia, Canada, and Zimbabwe, and mineral-rich brine, the salty underground water found beneath the salt flats of South America and in oilfield and geothermal formations worldwide. 

A third source, lithium-bearing clay, is in earlier stages of development. How lithium gets from the ground to a battery depends on which of these sources it comes from, and increasingly, on which technology is used to extract it.

 

Why Lithium is Important in the 21st Century

Lithium is the backbone of the modern energy transition. It is the lightest metal and the lightest solid element in the periodic table. Those properties make it uniquely well suited to rechargeable battery technology: high energy density, low weight, and the ability to charge and discharge thousands of times.

Batteries now account for approximately 87% of global lithium end use, up from a small fraction two decades ago. That shift has been driven almost entirely by electric vehicles and grid-scale energy storage. 

Global lithium demand is forecast to reach approximately 3 million tonnes of lithium carbonate equivalent by 2030, more than ten times the roughly 260,000 tonnes produced in 2025. The pressure on supply, and on the countries and technologies that can deliver it, has never been greater.

 

The Origins of Lithium

Lithium is found in most igneous (magma-based) rocks in small quantities, as well as in natural brines. Concentrated, extractable deposits are rarer, forming only under specific geological conditions over millions of years.

Hard Rock (Spodumene Pegmatites)

Hard rock lithium is extracted from pegmatites, coarse-grained igneous rocks formed during the final stages of magma cooling. Spodumene is the most abundant and commercially important lithium-bearing mineral, alongside lepidolite and petalite.

Spodumene deposits are found across Australia, North America, Europe, Africa and South America, making them the world’s most widespread lithium resource.

Extraction involves conventional mining, followed by crushing, roasting and chemical processing to produce battery-grade lithium compounds. While well established, this method is energy intensive and has a relatively large environmental footprint.

Brine Deposits

Lithium brines form when groundwater dissolves lithium from surrounding rocks and concentrates it in underground aquifers over millions of years. These deposits are most common beneath the salt flats of Chile, Argentina and Bolivia’s Lithium Triangle, although significant resources also exist in China, North America and Europe.

Compared with hard-rock mining, brine extraction generally has a lower environmental footprint. However, traditional evaporation ponds require large volumes of water and long processing times, driving interest in more efficient technologies such as Direct Lithium Extraction.

Clay Deposits (Emerging)

Lithium can also be extracted from clay minerals, particularly hectorite, as well as petroleum brines, often called petrolithium. These resources remain largely pre-commercial, although projects in Nevada and Serbia are among the most advanced. 

As extraction technologies improve, clay deposits could become an increasingly important source of future lithium supply.

 

The World’s Largest Producers of Lithium

Global lithium supply is highly concentrated, with three countries, Australia, Chile, and China, accounting for the majority of production. Australia currently produces the largest volume of lithium at 36% of the global supply.

Reserves, the resource that could be mined economically with current technology, tell a different story, with South America holding the largest known concentrations.

 

Country Primary source Share of global production Notable resource
Australia Hard rock (spodumene) ~36% Greenbushes mine, Western Australia (world’s largest hard-rock lithium mine)
Chile Continental brine ~22% Salar de Atacama
China Mixed (hard rock + brine) ~16% Significant domestic reserves plus control of ~60% of global refining capacity
Argentina Continental brine ~10% Multiple Lithium Triangle salars
Bolivia Continental brine Small but growing Salar de Uyuni (estimated ~50 million tonnes of resources, the largest single deposit on Earth)
United States Brine (oilfield + geothermal + salar) Currently less than 1% Smackover Formation (TX), Great Salt Lake (UT), Salton Sea (CA), Appalachian Mountains

Emerging Producers

Canada, Zimbabwe, Mali, and Brazil are all growing contributors to global supply, primarily through hard-rock mining. Portugal and several African nations are in earlier stages of development. 

The next significant shift in the supply landscape is expected from the United States and Argentina, both of which have large resource bases and active development pipelines.

The Lithium Triangle: Chile, Argentina, and Bolivia

The Lithium Triangle is the world’s most important brine lithium resource. 

Chile’s Salar de Atacama is a major global lithium brine operation, with production led by SQM and Albemarle.

Argentina is the fourth-largest producer globally and growing rapidly, with multiple salar projects in development. 

Bolivia’s Salar de Uyuni holds the largest estimated single lithium resource on Earth, approximately 50 million tonnes, but development has lagged due to policy constraints and the technical challenge of processing its high-magnesium brine.

ÐÓ°ÉPro’s Project Black Giantâ„¢ is located at the Salar de Punta Negra in Chile, covering approximately 90,000 acres of lithium resource. Goldman Sachs serves as financial adviser, and the U.S. EXIM Bank has issued a Letter of Interest to support project financing.

Where Does the United States Get Its Lithium?

The United States imports more than 90% of its lithium, primarily from Chile and Argentina, while domestic production remains limited to the Silver Peak brine operation in Nevada.

Despite this reliance on imports, the U.S. has significant untapped lithium resources. The Smackover Formation in Texas and Arkansas, Utah’s Great Salt Lake basin and California’s Salton Sea all contain substantial lithium-bearing brines.

ÐÓ°ÉPro’s Project Lonestarâ„¢ in Hooks, Texas is among the first DLE facilities in the United States to reach active production. It processes approximately 250 metric tonnes per year of battery-grade lithium carbonate equivalent from Smackover oilfield brine, establishing the technical and economic proof points for the formation as a serious domestic supply source.

The Environmental Impact of Lithium Mining

Both hard-rock mining and brine extraction have environmental trade-offs.

Hard-rock mining is the more carbon-intensive method, requiring large-scale excavation, energy-intensive processing and chemical treatment. Brine extraction generally has a lower carbon footprint but traditional evaporation ponds consume large volumes of water and can affect sensitive ecosystems in arid regions.

Direct Lithium Extraction addresses many of these challenges by extracting lithium without large evaporation ponds. ÐÓ°ÉPro’s ³Ò·¡°Õ-³¢¾±³Ùâ„¢ platform uses little to no freshwater, avoids heavy chemical additives and reinjects spent brine back into the aquifer, helping reduce water loss while improving lithium recovery.

As ÐÓ°ÉPro’s Vice-President of Growth Strategy, Milda Saenz, has put it: “Lithium extraction and its associated operations have been linked to environmental and socio-economic pressures around the world. Considering the vast amount of lithium that is needed to meet global goals on clean energy and the associated fight against climate change, decision-makers cannot afford for lithium extraction to continue as ‘business as usual’. It is for this reason that ÐÓ°ÉPro is disrupting the mining industry by creating technology that improves lithium yields and reduces environmental impacts.”

ÐÓ°ÉPro’s approach to sustainability and environmental stewardship is outlined on our company’s sustainability page, including the closed-loop brine management principles behind both Project Lonestarâ„¢ and Project Black Giantâ„¢.

ÐÓ°ÉPro to Boost US Lithium Production

ÐÓ°ÉPro is already producing battery-grade lithium from domestic U.S. brine. Project Lonestarâ„¢ in Texas is operating today. 

Project Black Giantâ„¢ in Chile is backed by some of the world’s leading financial institutions. 

The ³Ò·¡°Õ-³¢¾±³Ùâ„¢ platform, developed over years of field deployment and supported by 100+ issued or pending patents, is the technology bridge between where lithium is found and where it needs to go.

Frequently Asked Questions

Which country produces the most lithium?

Australia is the world’s largest lithium producer by volume, accounting for approximately 36% of global supply, almost all of it from hard-rock spodumene mines in Western Australia. 

Chile is the second-largest producer at around 22%, extracting lithium from the brine deposits of the Salar de Atacama. In terms of known reserves, Bolivia and Chile hold the largest concentrations, in the brine-rich Lithium Triangle region.

Who is the biggest buyer of lithium?

China, by a considerable margin. EVs account for approximately 70% of global lithium battery use, and China is the world’s largest EV market and battery manufacturer. 

China also controls approximately 60% of global lithium refining capacity. That makes it central to the supply chain not just as a consumer but as the dominant processor of raw material from Australia, South America, and elsewhere.

Will we run out of lithium?

Not on any near-term horizon. Global reserves are sufficient for decades of supply at projected demand growth rates, and DLE technology is expanding the accessible resource base by unlocking brine sources that traditional evaporation methods cannot process economically. 

Battery recycling will add a growing secondary supply stream through the 2030s. The real challenge is not total abundance but the speed and geography of supply development, which is precisely why domestic projects and next-generation extraction technology matter.
