CMI researchers from Ames National Laboratory conducted the activity for this highlight

Innovation 
Mechanochemical process to extract 85%+ of Lithium available in domestic hard-rock ore diversifying lithium supplies.

Achievement
Published a review article titled “Aspects of Spodumene Lithium Extraction Techniques” (39 pages), which provides a comprehensive analysis of current methods for lithium extraction from spodumene, highlighting key advancements, challenges, and opportunities.

Significance and Impact

  • Elimination of the high-temperature thermal-decrepitation step.
  • Replaces harsh acid/alkaline solutions with mild alternatives.

Hub Target Addressed 
Recovery and conversion of critical minerals into high-value end products; industry adoption of technology for the source-diversification of Lithium enhancing energy security.
