The isodynamic field, generated by a bipolar magnet with special pole tip profiles, provides constancy of the product of the field and the field gradient. However, mineral separation in an isodynamic magnetic field is limited to minerals that have a constant susceptibility at the laboratory scale.
Magnetic separation has wide-ranging applications in both mineral processing and recycling industries. Nevertheless, its conventional utilization often overlooks the interplay between mineral and particle characteristics and their impact on operational conditions, ultimately influencing the efficacy of the separation process. This work describes a methodology able to …

The work in this paper describes the creation of a batch laboratory separator through modifications to a Frantz isodynamic magnetic separator. The separator allowed the rapid separation of coarse (600–850 μm) particles based on relative density. ... Magnetohydrodynamic and magnetohydrostatic separation — a new prospect for mineral ...
Frantz Isodynamic Separator, has been used for the separation of various non- sulphides from each other. Its application to the separation of sulphides, however, does not seem to have been reported. In the Richards Mineral Dressing lab- oratories, the success achieved through the use of this device in separating associated
The sink and float studies indicate a negligible improvement in mineral liberation arising due to the thermal treatment while the Frantz isodynamic separation results suggest a remarkable increase in the mass magnetic susceptibility value from 14.4 × 10 −9 to 30 × 10 −9 SI units for the treatment at 500 °C. Detailed mineralogical ...
MineralMate is a standalone MATLAB-based program designed to optimize the workflow associated with the magnetic separation of minerals. For nearly every bulk geochemical analysis some amount of mineral separation must occur, and the use of an electromagnetic separator is ubiquitous and considered as standard practice in many fields.
Magnetic separation of heavy mineral fraction on a Frantz isodynamic separator is also known to shift the age spectra in detrital samples with the preference for less magnetic and less discordant zircon grains …

A calibration of the Frantz isodynamic magnetic separator relates the current in the electromagnet and the transverse slope of the chute to the specific susceptibility at which separation is being effected. In addition to providing a rapid measure of the specific susceptibility of minerals and composite grains, the calibration provides a guide to operation of the Frantz isodynamic …

These will be the different levels of amperage used to separate the minerals. This would also be a good time to get out 5 glass vials, and label them all with your sample name. They should also be labeled as: "Fr. 1.5 amp non-mag", "Fr. 0.1 amp mag", "Fr. 0.5 amp mag", "Fr. 1.0 amp mag", and "Fr. 1.5 amp mag".
Furthermore, magnetic separation methods may be used in the discovery of ore deposits rich in magnetic minerals like magnetite, hematite and other heavy minerals.
