PROBLEM TO BE SOLVED : To provide systems and methods for recovery of rare-earth constituents from environmental barrier coatings.SOLUTION : A method for separating rare-earth (RE) containing constituents from particulate feedstock containing a mixture of rare-earth silicates and non-magnetic constituents includes disposing a collection member in a vicinity of the feedstock and magnetizing the collection member to generate a magnetic field sufficient to selectively attract the rare-earth silicates to the collection member. The method further includes removing the rare-earth silicates from the collection member.COPYRIGHT : (C)2016, JPO&INPIT
