  • Mineral separation laboratory University of Bergen

    Apatite is mostly used for fission track dating (thermochronology). Frantz magnetic separator: Magnetic separation is based on minerals` magnetic properties. Some of the largest and magnetic minerals (ferromagnetic minerals) are often removed via a handheld magnet before they are sent through the magnetic separator.

    Using a magnetic field of up to 20,000 Gauss, we are able to separate minerals that are only slightly magnetic. Of the heavy minerals that we typically encounter, garnet and clinopyroxene are separated at low magnetic fields in the first several passes, followed by titanite and monazite, and finally zircon, apatite which are non magnetic. 5.
