CMI researchers from Lawrence Livermore National Laboratory and Ames National Laboratory conducted the activity for this highlight
Innovation
Scaling lanmodulin (LanM) column enables single-stage Dy separation from a mixed rare earth oxide (REO) prepared from a Nissan Leaf motor using the Acid-free Dissolution Recycling (ADR) process.
Achievement
Scaled LanM column from 5 cm to 20 cm. In a single adsorption/desorption cycle starting with a solution prepared from REO with 13% Dy, increasing length improved content and yield.
Significance and Impact
Suggests that separation efficiency may improve as the LanM separation process is scaled.
Next Steps
Test a range of mixed REO compositions produced by the ADR process and use this data as a baseline to evaluate the performance of size-reduced LanMs.
Hub Target Addressed
Sustainable method for REE recycling from end-of-life consumer products.
