A millennial is building America’s first nickel-cobalt refinery

Kaleigh Long believed there had to be an American fix. As an Oklahoman working on political campaigns in the Democratic Republic of Congo she saw all too closely the bloodiness of the critical-mineral trade. Militias killed her flatmate’s siblings, burnt homes on resource-rich land and forced children to dig in the mines—as Chinese companies tolerated the abuses.Back home the 28-year-old single mother reckoned that getting into the mineral business was the best way to clean up the supply chain and ease China’s chokehold on cobalt and other minerals vital to a greener economy. America had no nickel-cobalt refineries of its own. In early 2022 Ms Long set out to build its first. She raised $50m for her startup, Westwin Elements, and recruited oil-and-gas tycoons, a former intelligence officer and the longtime boss of Boeing, an aerospace company, to sit on her board. In her Oklahoma City headquarters the self-described libertarian touched her necklace, the pendant a silhouette of Africa, as she spoke about the $185m grant Westwin next hopes to win from the Department of Energy.
