Major Lithium Ores: Hard Rock Minerals

Hard-rock lithium is primarily extracted from pegmatite intrusions, which are coarse-grained igneous rocks formed from late-stage cooling of silica-rich magma. These pegmatites can be rich in lithium-bearing minerals, with several types being commercially significant worldwide.

Spodumene

Spodumene (LiAlSi2O6) is the most important and abundant hard-rock source of lithium globally. It is a pyroxene mineral that typically occurs in lithium-cesium-tantalum (LCT) pegmatites. Spodumene crystals are often prismatic and can be white, gray, or greenish. The key producers of spodumene are Australia (particularly Western Australia), Canada, China, and several African nations. Australia is by far the world’s largest producer of spodumene concentrate.

Petalite

Petalite (LiAlSi4O10) is another lithium-bearing silicate mineral found in some LCT pegmatites. While it contains lithium, its concentration is generally lower than spodumene, and it can be more challenging to process. Significant petalite deposits are found in Zimbabwe, Namibia, and some locations in South America. It is often found in association with spodumene.

Lepidolite

Lepidolite is a lithium-rich mica mineral, often characterized by its distinctive purple or pinkish hue. It is typically found in lithium-bearing pegmatites but usually contains lower lithium concentrations compared to spodumene and petalite. Lepidolite is generally considered a minor source of lithium, often recovered as a byproduct rather than a primary target.

Amblygonite

Amblygonite, a lithium aluminum phosphate mineral ((Li,Na)AlPO4F,OH)), can have a high lithium content. However, deposits are generally smaller and more scattered than spodumene occurrences, making large-scale commercial extraction less common. It is found in various pegmatite and granitic environments worldwide.

Hard Rock Mining Regions

Key global regions for hard-rock lithium mining include the Greenbushes mine in Western Australia (one of the world’s largest and highest-grade spodumene deposits), various operations in Canada (e.g., Quebec), and developing projects in regions like Africa (e.g., Mali, Zimbabwe) and South America. The United States also has historical and potential spodumene deposits in states like North Carolina and South Dakota.

Major Lithium Ores: Brine Deposits

Lithium brine deposits represent the other major source of global lithium production, particularly significant in South America and increasingly in geothermal sources. These brines are naturally occurring saline waters with elevated concentrations of dissolved lithium.

Salar Brines

Salar brines are found in arid, endorheic (closed) basins, where water evaporates faster than it flows out, concentrating dissolved salts, including lithium. The most significant salar deposits are located in the “Lithium Triangle” of South America: Chile (Salar de Atacama), Argentina (Salar del Hombre Muerto), and Bolivia (Salar de Uyuni). These regions benefit from high evaporation rates and lithium concentrations.

Geothermal Brines

Lithium can also be extracted from geothermal brines, which are hot, mineral-rich waters found deep underground, often associated with volcanic activity. The Salton Sea region in California, USA, is a prime example of a geothermal area with significant dissolved lithium content in its brines. Advances in Direct Lithium Extraction (DLE) technologies are making geothermal brine extraction increasingly viable.

Oilfield Brines

In some regions, lithium is found dissolved in formation waters associated with oil and gas fields. As these waters are often extracted during oil and gas production, recovering lithium from them can represent a valuable secondary revenue stream and utilize existing infrastructure.

Brine Extraction Methods

Traditionally, lithium is extracted from salars using solar evaporation ponds. This method involves pumping brine into large ponds where the sun’s heat evaporates water over many months, concentrating the lithium salts. While cost-effective in suitable climates, it is slow and requires large land areas. Emerging Direct Lithium Extraction (DLE) technologies aim to overcome these limitations by selectively removing lithium directly from the brine using methods like adsorption, ion exchange, or membranes, offering faster processing and potentially lower environmental impact.

Key Lithium Producing Countries and Regions

The global supply of lithium is concentrated in a few key countries, driven by their geological endowment of rich ore and brine deposits, as well as their capacity for extraction and processing. Understanding these leading regions is vital for analyzing global supply dynamics and market trends, particularly as demand continues to surge towards 2026.
