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
The MELLT (Mechanochemical Extraction of Lithium at Low Temperatures) technology is a 2024 R&D 100 Finalist, an honor that highlights it as one of the most innovative technologies of the year. Of 141 cutting-edge projects selected worldwide, MELLT stood out for its exceptional potential to revolutionize the extraction of lithium from domestic hard-rock ore.
Significance and Impact
- Eliminates the high-temperature thermal-decrepitation step,
- Replaces harsh acid/alkaline solutions with mild alternatives, and
- MELLT offers a viable alternative to traditional energy- and waste-intensive methods, greatly reducing energy costs.
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.
