CMI researchers from Oak Ridge National Laboratory conducted the research for this highlight.
Innovation
Develop techniques for synthesis of large monazite crystals to enable analysis of properties of specific crystal faces for improving mineral separation.
Achievement
Synthesis of relatively large single crystals of lanthanum monazite.
Significance and Impact
- Large monazite crystals allow experimental interrogation of the mineral surfaces by laser spectroscopy, adsorption, and other techniques.
- Understanding surface properties and adsorption behavior enables the design of mineral-specific flotation collector molecules for selective beneficiation.
- Synthetic crystals do not contain the radioactive thorium common in natural crystals, allowing work in non-rad environments.
- Next steps include laser spectroscopy and adsorption studies.
Hub Goals Addressed
Unlocking unconventional resources. Highly selective separation from complex sources.
