Separating metals out of a magnet I have acquired the crushed magnet out of a motor I was given. If I'm correct that the magnet is $\ce{NdFeB}$ magnet, how could I separate out all the metals into a pure or oxide form? And for hard drive magnets, is there any way to remove the $\ce{Ni}$ coating without having to get nitric acid?  I don't have any proper chemistry equipment at all.
From this paper,  it seems Electrochemical recovery of Neodymium is possible from the Magnet.
