CMI researchers from Idaho National Laboratory conducted the research for this highlight.
Innovation
Electrochemistry-mediated process has been proved to leach Idaho cobalt concentrate containing arsenic at low temperature and ambient pressure.
Achievement
- 99% leaching yield for both cobalt and arsenic from Idaho’s cobalt concentrate provided by Jervois Mining.
- Development of preliminary leaching parameters.
- Obtention of a Co/As concentrate solution to follow up with the As removal as scorodite waste form.
Significance and Impact
- Improves the leaching yield of mining concentrate.
- Potential to replace existing high pressure/high temperature process to process sulfide minerals.
Hub Target Addressed
Unlocking unconventional resources of critical materials.
