Magnetic Separation Of Magnetite

  • Difference Between Magnetite and Hematite | Definition ...

    Jan 31, 2018· Magnetite and hematite can be separated from each other using their magnetic properties. Magnetite is ferromagnetic and hematite is paramagnetic. Therefore, these substances can be separated using low-intensity magnetic separation method. Here, an induced roll magnetic separator with a magnetic field with a 0.04 Tesla intensity is used.
