Abstract

Methods and systems for the extraction of magnetic material from magnet containing material, and for extraction of rare earth elements (REEs) from the magnetic material are disclosed. An exemplary system includes a milling unit for magnet containing material such as end-of-life motors, hard drives, partially deconstructed motors, magnet-containing end-of-life product, or parts thereof, and outputting magnetic components by exploiting magnetic properties of ferromagnetic and paramagnetic materials in the presence and absence of electromagnetic fields in conjunction with other physical properties such as size and density. The system also includes a chemical processing unit for receiving the magnetic components to extract rare earth elements in the material. Chemical processes are disclosed for separating and recovering rare earth elements, iron, mixed hydroxide precipitate (e.g., nickel, cobalt), and/or boron, from magnetic components.
