US critical minerals plant targets 2,250 metric tons of lithium to power defense, EV

US-based Aqua Metals has signed a six-year letter of intent with commodity trader WMC Group. The deal covers all lithium carbonate planned from the upcoming Project Headwaters plant in the American Midwest. This site represents the first full-scale commercial use of the company’s AquaRefining system. The technology extracts battery-grade materials from spent batteries using electrochemistry instead of high-heat smelting. Most battery recycling plants rely on pyrometallurgical smelting. These systems burn shredded battery scrap at very high temperatures. While smelting recovers nickel and cobalt, it burns away lithium or leaves it trapped in slag. The alternative approach is hydrometallurgy, which dissolves the metals in acid. However, traditional hydrometallurgical plants consume large volumes of one-time chemical reagents. These chemicals produce substantial hazardous waste, including sodium sulfate salt cakes that require landfill disposal. A closed-loop circuit AquaRefining operates through a closed-loop, room-temperature circuit. It treats “black mass,” the powder created when spent lithium-ion batteries are crushed and shredded. The process uses electricity rather than consumable acid-base neutralizers to recover the dissolved metals. Within the cells, electricity plates out pure elemental metals and selectively precipitates battery compounds like lithium carbonate. Because the chemical bath regenerates continuously during the electrical cycle, the facility avoids producing the massive liquid and solid waste streams common in older plants. Project Headwaters aims to start operating in 2028 with an initial output of 250 metric tons of lithium carbonate. Production plans call for a steady ramp to 2,250 metric tons each year by 2032. Over the six-year span, the site is designed to deliver roughly 7,000 metric tons of the compound. That volume holds an estimated market value of 135 million dollars, though final revenue will reflect prevailing metal spot prices and purity checks. The non-binding agreement with WMC Group also covers refined nickel and cobalt. Both companies plan to sign a final, binding contract by September 30, 2026. Plans for feedstock sourcing, too Aside from raw product sales, the firms are setting up joint plans for feedstock sourcing and tolling arrangements. Under tolling agreements, third parties deliver raw black mass to the site to be refined for a processing fee. The partnership arrives just as federal rules force battery scrap to stay inside the United States. Under the Defense Production Act, the White House classified recycled battery minerals as industrial materials critical to national security. In addition, the Bureau of Industry and Security enacted a rule requiring scrap processors to sell black mass entirely to domestic firms. American battery recyclers can no longer export unprocessed black mass overseas, creating immediate demand for domestic refining plants that can turn raw scrap into finished precursor chemicals. Completed the first commercial sale This processing capacity carries strategic utility beyond waste management. By generating a local supply of low-cost refined minerals, facilities like Headwaters directly feed domestic battery manufacturing, energy storage grids, defense systems, and electric vehicle production. Aqua Metals recently completed its first commercial sale of recycled lithium carbonate to an American buyer at market rates. The transaction confirmed that chemically recycled lithium meets the chemical tolerances needed for battery manufacturing. Beyond the Midwest plant, Aqua Metals and WMC’s partner, Liminal, are reviewing options to license the electrochemical technology for planned processing sites in Canada and the Netherlands.
