Lithium's story is usually told as a single triangle in the Andes. The extraction data says something more layered: three distinct physical mechanisms, spread across three continents, none of them dominant in the way a single dramatic name ("Lithium Triangle") implies.
The Lithium Triangle spans Argentina, Bolivia, and Chile, defined by three salt-pan vertices: Salar de Uyuni (Bolivia), Salar de Atacama (Chile), and Salar del Hombre Muerto (Argentina). Chile's Salar de Atacama holds the highest brine concentration of any lithium source on Earth — 0.15% by weight. As of 2017 the region held an estimated 54% of world lithium reserves.
But the source itself corrects its own name: the actual area of interest runs as a crescent from Salar de Surire (19°S) down to Salar de Maricunga (27°S) — not a triangle at all. Geologists have proposed renaming it the Lithium Crescent.
Reserves and extraction diverge sharply inside this one region:
Country 2022-24 Production Notes --------- ------------------ ----- Chile 49,000 t Highest brine concentration on Earth Argentina 18,000 t Salar del Hombre Muerto Bolivia 540 t Holds vast reserves, extracts almost none
Bolivia sits at one vertex of the very triangle named for this deposit and produces a fraction of a percent of what Chile does from the same kind of reserve — reserve size and extraction rate are not the same thing, and the gap between them is itself the finding.
The single largest lithium-producing country in the world by tonnage is not part of the Triangle at all:
Rank Country 2024 Production ---- ----------- --------------- 1 Australia 88,000 t 2 Chile 49,000 t 3 China 41,000 t 4 Argentina 18,000 t 5 United States 5,000 t
Australia extracts lithium by an entirely different physical mechanism — not evaporation ponds, but hard-rock mining of spodumene, a lithium aluminium silicate mineral. The country's flagship deposit, Greenbushes in Western Australia, began as an 1886 tin-mining town and only later became a lithium site; it is reported as the world's second-largest spodumene source and the highest-grade ore body known, at 2.4% Li2O.
Two structurally different extraction methods — slow solar evaporation of brine versus direct rock extraction — produce comparable tonnages on opposite sides of the planet, and the country most associated with lithium in the public imagination (via the Triangle) is not the country that actually mines the most of it.
China ranks third in raw extraction (41,000 t) — a real but secondary position. Its actual grip on the lithium supply chain runs through ownership, not geography, exactly the mechanism this run's polysilicon research found in solar manufacturing, but taking a different corporate shape here: cross-border equity stakes rather than domestic refining capacity.
Tianqi Lithium, a Sichuan-based company, controlled more than 46% of world lithium production as of 2018 — not by mining most of it inside China, but by owning:
- a 51% stake in Talison Lithium, which operates Greenbushes,
Australia's own flagship hard-rock mine (since 2009)
- a 24% stake (~$4.1B) in SQM, the Chilean mining company that
works the Salar de Atacama brine deposit at the very heart of
the Lithium Triangle (2018)
One Chinese company thus holds a direct financial stake inside BOTH of the other two mechanisms mapped above — the Australian hard-rock mine and the Chilean brine operation — without China itself needing to be the country where either deposit physically sits.
EXTRACTION OWNERSHIP

~0 from Bolivia

world at 88,000t Talison/Greenbushes

of the above
Lithium has no single geography the way coal or oil does. It has three separate, physically distinct mechanisms operating simultaneously: solar-evaporated brine in an Andean crescent misnamed a triangle, direct rock extraction led by a country outside that crescent entirely, and a Chinese company's equity stakes reaching physically into both of the other two without mining the most lithium itself. The element is the same everywhere; the way it is pulled out of the ground, and the way it is owned once pulled out, are not.
