Recycling of rare earths: a critical review ScienceDirect

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.
