Chemical and Mining Co of Chile
SQM, led by CEO Ricardo Ramos, controls roughly 20% of global lithium output from Chile's Salar de Atacama — the richest lithium brine deposit on earth.
Chemical and Mining Co of Chile
Founded in 1968 as a state-owned enterprise, Chemical and Mining Co of Chile — SQM — was privatized in the 1980s and is now controlled by Julio Ponce Lerou, former son-in-law of Augusto Pinochet, alongside Chinese lithium giant Tianqi Lithium, which holds a significant minority stake. The firm operates from Santiago with its flagship asset in the Salar de Atacama, a high-altitude salt flat in northern Chile containing the world's highest-concentration lithium brine. SQM's wealth is anchored in geology and political access — its brine-extraction rights run through CORFO, the state development agency, giving the Chilean government direct leverage over output volumes. SQM's deployment is overwhelmingly capex-driven, pumping brine to evaporation ponds and refining lithium carbonate and hydroxide for battery-cathode manufacturers. The lithium segment serves offtakers including LG Energy Solution, SK Innovation, and CATL, linking SQM directly to North American, European, and Asian EV supply chains. A parallel specialty plant-nutrition business produces potassium nitrate, iodine, and solar salts — the iodine operation alone holds roughly 30% of global market share. Geographies span Chile, with distribution into China, Korea, Japan, Europe, and the United States. The firm also operates a lithium hydroxide conversion plant in Australia through a joint venture with Wesfarmers at Mt Holland. SQM employs roughly 7,000 people and runs three primary business lines: lithium and derivatives, specialty plant nutrition, and industrial chemicals. As of March 2024, SQM announced a joint venture with state-owned copper giant Codelco to consolidate lithium operations in the Salar de Atacama under a public-private partnership set to take effect in 2025, extending SQM's operational footprint through 2060. The firm has aggressively grown lithium production from 70,000 metric tons in 2021 to a projected 210,000 metric tons of carbonate capacity by 2025 through on-site expansions in Antofagasta. SQM's structural differentiator is its hybrid posture — a publicly traded commodity producer with a government-mandated operating lease, operating like a national champion stitched onto global EV supply chains. The upcoming Codelco JV deepens state partnership rather than retreating from it, creating a governance model rare outside Chile: a private company sharing output, revenue, and strategic direction with a state mining enterprise while maintaining NYSE listing and Western-offtaker access.

Frequently asked questions
Who controls SQM?
SQM is controlled by Julio Ponce Lerou through a series of holding companies, with Chinese lithium producer Tianqi Lithium as the second-largest shareholder holding roughly 22% of voting shares. Ponce's stake traces back to the firm's privatization during the Pinochet-era state-asset sell-offs in the 1980s, creating an ownership structure that has been the subject of longstanding governance scrutiny.
How does SQM source its lithium, and what gives it a cost advantage?
SQM extracts lithium by pumping subsurface brine from beneath the Salar de Atacama into vast evaporation ponds, where solar concentration separates lithium from other salts. The Atacama brine holds the highest known lithium concentration globally, giving SQM a structural cash-cost advantage over hard-rock miners in Australia and brine operators in Argentina. The process relies on an extraction lease from CORFO, which imposes production quotas and royalty payments.
Is SQM a mining company or an asset manager?
SQM is a listed specialty-minerals producer, not an asset manager. The firm is a publicly traded company on the NYSE and Santiago Stock Exchange. It appears in Altss mapping because cursory database classifications sometimes label corporate holding structures as asset managers, but the entity itself operates physical brine extraction, processing plants, and direct B2B commodity sales.
What does the 2024 Codelco joint venture mean for SQM's long-term access to lithium reserves?
The agreement with Codelco, the world's largest copper producer and a Chilean state-owned enterprise, consolidates Atacama lithium operations under shared ownership beginning in 2025. In exchange for accepting state partnership, SQM's operational rights in the salar extend from 2030 to 2060. The government receives increased revenue through higher royalty rates and a seat at the table on future capacity decisions.
Who are the major customers for SQM's lithium?
SQM holds long-term supply agreements with major battery-cathode and EV-manufacturer supply chains including LG Energy Solution in Korea, SK Innovation, and China's CATL. The firm supplies both lithium carbonate and lithium hydroxide, with a growing share of hydroxide production aimed at higher-nickel cathode chemistries preferred in Western EV platforms. Customers are disclosed in regulatory filings with the Chilean securities commission.
