New Life for old scrap

Apparently the neodymium in those rare-earth magnets cant be simply remelted and cast into new magnets, according to this article there are stockpiles all over, of rare-earth magnet waste waiting for someone to figure out something to do with it. The metal is also used in magnesium casting, and accounts for a large % of the castings value. Two smart people figured out u can leach the neodymium from the iron in the magnet scrap directly into molten magnesium, giving what they say the casting industry already wants. So maybe if this process is picked up by companies and made viable, this stuff will have value not just as iron scrap...
