Magnetic separators used during the study were Frantz Isodynamic Magnetic Separators, Model L-1*. The original brass chute in each machine was replaced by an aluminum chute milled in the USGS machine shop. The isodynamic vibrator at the upper end of the chute was replaced by an asymmetric vibrator, as described by Faul and …

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 …

The Frantz Isodynamic Magnetic Separator (FIMS) is a versatile instrument and can produce excellent concentrates of many minerals. Substantial literature has been published on the subject of mineral separations performed with the FIMS [Citations omitted]. The MBLS has a significant advantage over the FIMS in the ratio of magnetic force to field ...

The samples are prepared as magnetite-free feed and then is subjected to heavy mineral separation using Frantz Isodynamic separator to determine the behaviour of each mineral during magnetic separation. For magnetic separation, first magnetite and other strong magnetic minerals were separated with the help of a hand magnet, then …

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 experiments in Frantz isodynamic magnetic separator were carried out to calculate the mass magnetic susceptibility of the iron ore particles following a standard procedure documented elsewhere [22]. The side slope of 15° was set constant and the current was varied from 0.4 to 1.0A. About 1 g of sample having a particle size of …

Mass magnetic susceptibilities of thirty-eight trioctahedral micas were determined using a Frantz Isodynamic Separator. Comparison of the data to partial chemical analyses indicates clearly that the major con-trolling factor in determining magnetic susceptibility is the amount of iron present in the mica.

Magnetic separation of mineral particles depends on the magnetic susceptibility of the minerals to be separated. This is a complex phenom— enon which is a function of chemical composition, especially minor amounts of iron or manganese, and atomic—lattice structure. The simplest form of magnetic separation is by hand magnet, a
