Overview

Randomized trial investigates magnetic separation efficacy in recycling neodymium, indicating potential for cleaner technologies.

Key Points

  • This study aims to explore methods for effectively isolating neodymium-containing fractions from mixed materials using magnetic separation techniques.
  • Developed analytical and simulation models to investigate influencing parameters of magnetic separation.
  • Examined transition from ferromagnetic to paramagnetic behavior for sorting based on Curie temperature.
  • Analyzed fine sorting in an inhomogeneous magnetic field without thermal influence.
  • Identified key parameters influencing magnetic separation efficiency, enhancing isolation of neodymium fragments.
  • Demonstrated potential synergies with thermal demagnetization processes to improve sorting outcomes.
