The most commonly used magnetic separator is the Frantz Isodynamic Magnetic Separator. It consists of a large electromagnet, through which mineral mixtures are passed on a metal trough. By varying the strength of the magnetic field or the slope of the tough, different minerals can be separated.
The setting of the separator during this study was (25°) sideslope and (10°) tilt slope. The investigated heavy mineral concentrates, as the magnetic fraction in the range of 0.3, 0.5, 0.8, and 1.2 A of the Frantz Isodynamic separator.
strength required for separation of the mineral in the Frantz Isodynamic Separator at a fixed transverse slope (15 o) and its composition affords a rapid and an elegant method for the separation of orthopyroxenes. The composi- tion of any orthopyroxene in terms of the end members is readily determined ...

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. It may find application in "heavy liquid" analysis to characterize materials.
In the next step, a Frantz Isodynamic Separator was used to separate magnetic (M) and non-magnetic (NM) sub-fractions by applying successively increasing currents with 15° side slope and 10° forward slope: 1) a 1.1 amp current to collect arsenopyrite (M1.1 fraction), 2) further treatment of the NM1.1 sub-fractions at a 1.7 amp …

The magnetic susceptibility classes of each size class in Figure 4A are plotted together with the magnetic susceptibility measured using the MSB and the calibration curve of the Frantz isodynamic separator. The magnetic susceptibility …
To illustrate the comparability of MLA-based calculated and measured (Frantz-type isodynamic separator combined with MSB) values, susceptibility distributions created by both methods were constructed for each size fraction of the PM product.
Feeding of the material to the isodynamic separator was started after 4 h of warming time (warming of the coils effects the amperage). Unlike the usual way to describe a samples susceptibility based on a calibration curve of the isodynamic separator, the susceptibility of the created fractions was measured directly using a susceptibility balance.

The separator consisted of 2 energizing coils and a removable steel wedge-wire grid pack sitting between coils. The magnetic field intensity could be varied between 0-2 T. The batch type laboratory scale HGMS has a limited space for magnetic product in between its matrix material. Therefore, HGMS tests were conducted using 10 g of samples to
