CMI research on cover of journal: Sustainable urban mining of critical elements from magnet and electronic wastes

Alert
COVID-19 Updates and Resources Pandemic Recovery Updates and Information

CMI scientists at Ames Laboratory conducted this research in Reuse & Recycling with techno-economic analysis contribution from a CMI project in Crosscutting Research conducted at the University of Arizona and Purdue University. 

Achievement

Journal publication on the acid-free leaching process for recycling rare-earth elements and cobalt from waste magnet and e-waste materials is published and highlighted as a supplementary cover in ACS high impact journal (https://doi.org/10.1021/acssuschemeng.9b05741)

Significance and impact

The process allows for selective leaching of rare-earth elements and cobalt from magnet-containing materials (swarfs, decrepitated powder, e-wastes) and eliminates the use of volatile toxic acid, hence an environment-friendly process

Details and next steps

  • Optimize the process to enhance opportunity for technology transfer
  • Update techno-economic analysis to reflect the optimized process
  • Extend the principles of the technology to other application
