  • DIRECTED LASER ENERGY TO REDUCE METAL OXIDES
    Publication number: 20240043959
    Abstract: A system and method for producing an intermediate metal product without generating significant carbon dioxide emissions is described herein. A metal oxide heated by at least one laser, combined with a heated reducing agent, produce an intermediate metal product. Further processing may produce a metal, which may optionally be combined with at least one alloying element to produce a metal alloy and may have impurities removed. A resultant metal powder from even further processing may be produced.
