CMI Project 3.1.2 Biological separation of energy-critical rare earth elements Research Highlights

First demonstration of adjacent lanthanide separation by lanmodulin

CMI researchers at Lawrence Livermore National Laboratory conducted the research for this highlight

$Separation of equimolar Tb-Dy feed loaded to 3 mM tREE with (top) isocratic 10 mM HCl (pH 2.0) and (bottom) proprietary effluent. (right) Yield-purity curve showing the enhanced performance of the new separation scheme relative to HCl. The 95% purity Dy fraction can be upgraded to 99.5% purity in a second cycle.$
