    Jul 15 2013 · Highlights Less than 1 of rare earths in end-of-life consumer products are being recycled. Recycling can help to ensure a supply of the most critical rare earths. Valuable waste streams are magnets metal hydride batteries and lamp phosphors. Recycling of neodymium avoids overproduction of cerium and lanthanum. Recycling and primary mining of rare earths are complementary activities.

  • Magnetic Separation MethodMineral Processing Metallurgy

    Magnetic separation is a process used to separate materials from those that are less or non­magnetic. All materials have a response when placed in a magnetic field although with most the effect is too slight to be detected. The few materials that are strongly affected (magnetised) by magnetic fields are known as "Ferromagnetics" those lesser (though noticeably) affected are known as
