Neodymium magnets are a member of the Rare Earth magnet family and are the most powerful permanent magnets in the world. They are also referred to as NdFeB magnets, or NIB, because they are composed mainly of Neodymium Nd, Iron Fe and Boron B. They are a relatively new invention and have only recently become affordable for everyday use.

In 1995, GM sold Magnequench, the leading rare earth magnet manufacturer, to Chinese companies with close government relations. China immediately replicated the capability. This was a critical step for China from moving from a basic low-end material supplier to a highly capable producer of magnets, alloys, and metals needed in major industries.

Oct 29, 2014 I had email to Mr. Guo for rare earth magnet requirements. They replied my e-mail promptly, and were very professional. Mr. Guos team still continues to deliver rare earth magnets to our agreed specifications with a very high quality standard since 2012. His team is very professional and thorough with its work.
Rare Earth Magnet Recovery Machine for HDDs The electric motors in HDDs contain rare-earth magnets. These are called voice coil motors VCMs. Fig. 2 shows the process used to separate and recover the rare-earth magnets. While development of an HDD dismantler1 that removes VCMs from HDDs and demagnetizes them has already been completed,

Jun 22, 2021 Unlike prices for gold and silver, rare earth elements prices are hard to come by, as there is no widely used public exchange for rare earths.
Apr 25, 2017 The rare-earth elements REEs are considered as some of the most critical elements in the EU and the USA today. E-scrap, such as end-of-life neodymium magnets, could be a viable secondary source for the recovery of these elements. Neodymium magnets NdFeB consist of considerable amounts of Nd, Dy, Pr, and some other REEs, depending on the specific application.
Rare earth elements occur in many minerals but typically in concentrations too low to be refined in an economical manner the concentration of REEs in the Earths crust is estimated to be between 150 to 220 parts per million, which is higher than the concentration of other metals mined for industrial use, such as Cu or Zn.
