POSCO completes second lithium plant in Argentina, adding 23,000‑ton capacity
POSCO Holdings finished the upstream portion of its second lithium brine plant at the Hombre Muerto salt flat on 6 October. The new facility can produce 23,000 tonnes of lithium carbonate per year, raising total Argentine capacity to 48,000 tonnes. The project cost about $954 million and is part of a plan to reach 100,000 tonnes of lithium production by 2033, with downstream processing in South Korea slated for 2027.
Why it matters
POSCO says the added capacity moves it toward a 50,000‑ton annual lithium‑hydroxide system, supporting EV and energy‑storage demand. The company also noted a $700 million short‑term borrowing facility from IDB Invest to fund operations.
