New, environmentally friendly method to extract and ...

Oct 08, 2021· Low-grade sources of rare earth elements (REE), for example from industrial waste, typically contain many rare earth elements and other metals mixed together. The new method relies on a protein called lanmodulin (LanM) that first binds to all the rare earth elements in the source. Then other metals are drained and removed.
