"Azimi and her team are working with Nutrien, a major global producer of fertilizer, to develop techniques for extracting rare earth elements from an industrial byproduct called phosphogypsum. They have also partnered with Rio Tinto Alcan to harvest rare earth elements from a byproduct of the aluminum industry known as ‘red mud.’

“Both of these had been traditionally thought of as waste streams,” says Azimi. “While the percentage of rare earths in them is low, the tonnage available is high enough to make the economics attractive.”"

Globally there are 4/5 monazite waste streams at various stages of development, relatively easy beneficiation step to a high grade ore, one I've invested in very similar to Mt Weld in both suite & grade, and amenable to Ce depletion in concentration.

Only the very high grade hard rock deposits RE have any sort of economic future, and NTU definitely not one of them.
