  • Publication number: 20160068929
    Abstract: Sulfuric acid baking allows for the selective extraction of rare earth metals from scrap Nd2Fe14B magnets. This process has the advantage of making the high-value rare earth metals water soluble while converting the contained iron, around 70% of the magnet's mass, into stable and insoluble iron (III) oxide, eliminating the need for separating and precipitating iron from solution. The process also has the advantage of safely disposing of metalworking fluid contained in rare earth magnet machine waste, a troublesome contaminate from technical and environmental perspective.
