Did you know2023
SQM is publicly known as the world's leading lithium producer (EV batteries), but they also produce approximately 50% of the world's iodine — from the same Atacama Desert mining operations that produce lithium. Iodine from SQM's caliche nitrate deposits is used in: (1) iodinated CT contrast agents (ioversol, iohexol) — without which modern radiology cannot perform CT scans; (2) Betadine/povidone-iodine antiseptic — used in hospitals, surgery, and wound care globally; (3) potassium iodide tablets — the emergency nuclear radiation prophylactic distributed during nuclear events. SQM therefore controls both the primary input to EV battery cathodes (lithium) AND approximately half of the world's medical imaging contrast supply AND half the supply of nuclear emergency protection tablets — from the same desert brine in northern Chile. A supply disruption at Atacama simultaneously affects automotive electrification, global medical CT imaging, and nuclear emergency preparedness.

SQM (Sociedad Quimica y Minera de Chile) was created in 1968 as a Chilean state enterprise to exploit the Atacama nitrate deposits — historically the world's primary source of nitrate fertilizers before synthetic Haber-Bosch ammonia displaced them. Under Pinochet's privatization program in the 1980s, SQM's majority control was transferred to Julio Ponce Lerou, Pinochet's son-in-law, through a series of transactions that Chilean courts and regulators have repeatedly scrutinized as below-market transfers of a national resource. SQM's lithium deposits were not a primary focus when the Pinochet-era privatization occurred — lithium was an industrial specialty metal, not a strategic battery material. In 2018, Tianqi Lithium (Chinese, state-linked) acquired 24% of SQM for $4.07 billion, making China the second-largest shareholder of the world's highest-concentration lithium deposit. The Chilean resource that was privatized to a dictator's family under military rule is now 24% owned by the Chinese government's strategic battery supply chain investment arm.
