Erik Ronald wrote "The Curious Case of Metal Bias":
"There are several current studies by the U.S. Department of Energy and several universities looking at recovery of rare earth elements (REE) from coal waste. Eastern U.S. (Appalachian) coal ash contains recoverable concentrations of neodymium, europium, terbium, dysprosium, yttrium, and erbium. Some Appalachian coal ash contains over 600 ppm of total REE." More...
They have a REE deposit in the USA with a very high REE content. The content of REO in Mountain Pass is 8-12 %. Why do not they develop it and other deposits?
REE fall into the list of strategic and critical metals.
Instead, they finance projects with a content of 600 ppm REE to create a new technology.
Where is the logic?
