Ryan Ott, a scientist at Ames Laboratory and a member of the CMI research team, said that with an ever-increasing amount of discarded electronics globally, it made sense to focus on the most ubiquitous source of valuable rare earth magnets in that waste stream -- hard disk drives, which have a relatively centralized scrap source.
"There are a lot of ways to go about getting the rare-earth elements out of e-waste, and some of them are very effective, but some create unwanted by-products and the recovered elements still need to be incorporated into a new application," said Ott. "Here we have eliminated as many processing steps as we can, and go straight from the discarded magnet to an end product, which is a new magnet."
Scrapped - HDD - Magnets - Coatings
Scrapped HDD magnets are collected, then any protective coatings are removed....
