Recovery of rare earth elements from waste streams using membrane processes: An overviewRare earth elementsResource recoveryMembrane filtrationNanofiltrationRecovery of rare earth elements (REEs) has become an attractive process owing to the high costs and limited availabilities of REEs. In addition, the...
Tens of thousands of tons of rare-earth permanent magnet (REPM) wastes are produced worldwide every year. The recovery of rare-earth elements from the wastes can effectively reduce the exploitation of rare-earth minerals. The recovery of neodymium and praseodymium from a REPM waste is investigated...
The Department of Energy put out a request Monday for input on designing and building a commercial-scale facility capable of extracting rare earth elements and critical minerals from the billions of tons of waste produced by coal mining and power plants, with $140 million in federal funding. Ene...
The presence of REEs in Jordanian phosphate waste which currently dumped to the desert may have an economic value since large amount of phosphate rock are used in fertilizers industry annually. REE extraction from phosphate mine waste will not only improve the profitability of phosphate mine but ...

Use and Sourcing of Rare Earths Elements Rare earth elements (REEs) as defined by the International Union of Pure and Applied Chemistry (IUPAC) include metals characterized by similar properties, namely ...
The meaning of RARE EARTH is any of a group of similar oxides of metals or a mixture of such oxides occurring together in widely distributed but relatively scarce minerals.
Rare-earth elements (REEs) play a key role in modern societies as their usage keeps increasing in new technologies and green energy sources. However, they are also considered the most critical raw materials in the EU and the USA in terms of supply. There is an increased global interest in ...
Finding and extracting enough rare earth minerals to power the growing number of mobile phones is a tough challenge that can wreak havoc on the environment — but new techniques could help. Researchers say they have removed valuable rare earth elements (REE) from waste at high enough yields to...
