Separation anxiety: Magnetic metal recycling
Rare earth magnets are widely used in a range of gadgets, instrumentation and even toys but recycling the mixtures of metals from which the magnets are formed is difficult. Now, research published in the journal Angewandte Chemie offers a novel approach to the isolation of neodymium and dysprosium from dismantled magnets. The technique could ward off a future shortage of these metals.
