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.

Turnipseed Family Chair and Professor Ching-Hua Huang, left, and Ph.D. candidate Laura Stoy, right, published research outlining a new method for extracting rare-earth elements from coal fly ash. By Melissa Fralick Researchers from Georgia Tech's School of Civil and Environmental Engineering have discovered a way to extract rare-earth …

The trick is using organic acids produced by bacteria to do the hard work of extracting rare earth elements (REEs) from phosphogypsum. The researchers tried a number of bio-acid mixtures of mineral and organic acids to extract six REEs – yttrium, cerium, neodymium, samarium, europium and ytterbium. The phosphate rock waste they were working ...
