Engineered porous material recovers valuable rare earth elements from industrial wastewater
The membrane captured up to 195 milligrams of dysprosium per gram and released the metals with dilute hydrochloric acid for reuse, researchers said.

Engineered porous material recovers valuable rare earth elements from industrial wastewater
The rare earth elements that help power electric vehicles, wind turbines, medical imaging machines and other advanced technologies may be hiding in an unlikely place: industrial wastewater.
Raw material source Waste water: A chemically modified pore material can bind neodymium, gadolinium and dysprosium even with a large iron surplus. In laboratory tests, one gram of the material absorbed up to 195 milligrams of one of the metals. Before technical use, however, its durability and reuse must be improved. Houston (U.S.A.). Rare earths are stuck in powerful magnets for electric cars [...] The post Porous material gains valuable rare e…
Instead of being limited to treating waste water, a team at Rice University in the US considered dirty water basins as resources for the recovery of valuable materials from rare lands. This could eventually open up the possibility of recovering critical minerals whose supply is limited in different regions. [...]
