    Magnets containing substantial quantities of rare earth elements are currently one of the most sought-after commodities because of their strategic importance. Recycling these rare earth magnets after their life span has been identified to be a unique approach for mitigating environmental issues that originate from mining and also for sustaining natural resources. Sintered Neodymium-Iron-Boron Magnets Characteristic Units C // C Assemblies using these magnets can also be provided. HcB, Coercivity BHmax, Maximum Energy Product Br, Residual Induction HcJ, Intrinsic Coercivity °C 20°C 60°C 80°C °C °C °C.

      Adopting reliable magnet material, it is non-toxic and harmless Create different shapes you like anytime, anywhere Perfect for releasing stress . Neodymium Iron Boron Magnets. Dexter uses only licensed neodymium and licensed magnet materials for all applications. Sintered neodymium-iron-boron (Nd-Fe-B) magnets are licensed rare earth magnets which are the most powerful commercialized permanent magnets available today, with maximum energy product ranging from 26 MGOe to 52 MGOe.

      The neodymium-iron-boron compound resembles ceramic, so these magnets are very easy to break or crack. On the outside these magnets are coated using nickel for protection from corrosion. Caption. elements from the magnets. Lyman et al.6 used the leaching method and have obtained high recovery of neodymium (98%) by dissolving the scrap in sulfuric acid followed by using alkali hydroxides to precipitate double salts of neodymium which can be further treated to obtain neodymium oxide.

Our alternative recycling strategy is based on a method developed by Dr. Eric Schelter of the University of Pennsylvania Department of Chemistry and his research. Neodymium-iron-boron (NdFeB) magnets offer the strongest magnetic field per unit volume, and thus, are widely used in clean energy applications such as electric vehicle motors.

However, rare earth elements (REEs), which are the key materials for creating NdFeB magnets, have been subject to significant supply uncertainty in the past decade.

A neodymium magnet (also known as NdFeB, NIB or Neo magnet) is the most widely used type of rare-earth is a permanent magnet made from an alloy of neodymium, iron, and boron to form the Nd 2 Fe 14 B tetragonal crystalline structure.

Developed independently in by General Motors and Sumitomo Special Metals, neodymium magnets are the strongest type of permanent magnet. Hydrometallurgical methods include whole leaching of magnet scrap by Lyman and Palmer (Lyman and Palmer, ) who obtained a high recovery of neodymium (98%) by dissolving scrap in sulfuric acid followed by using alkali hydroxides to precipitate double salts of neodymium, which can be further treated to obtain neodymium by: 3.

2.Goudsmit has a wide selection of overbelt and suspension magnets that stand out in terms of their service life, robust construction, magnetic force and magnetic field depth. For product flows with sharp pieces of metal – which makes a belt conveyor a poor choice – Goudsmit has drum magnets, including special versions for handling scrap metal.
