Scientists may have discovered a new source of rare earth elements – and an environmentally friendly way to gather them

A waste product of the fertilizer industry might serve as a rich repository of rare earth elements. Researchers have devised a natural way to get these resources from phosphate rock waste. Their bacteria-based extraction method caused much less harm to the environment than current techniques that relied on synthetic acids.  The discovery came from the Critical Materials Institute (CMI). A research group of the Department of Energy, the CMI sought to strengthen local sources of resources critical to clean energy technology.  Read more....
