U.S. Radify targets rare earths with plasma refining, challenging China dominance

U.S. startup Radify Metals is developing plasma-based metal refining technology to challenge China-centred rare earth supply chains. The company aims to remove oxygen from rare earth oxides to produce pure metals using superheated hydrogen plasma, leaving water vapour as the only byproduct. Radify is developing reactors for neodymium and dysprosium and plans to scale from kilogram-per-day output to a 100 kg-per-day pilot. It has raised close to $3 million.
