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 Davis (1959).

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 …

Company Description by S. G. Frantz Co., Inc. Founded in 1935, S.G. Frantz® has been manufacturing magnetic separators for the removal of fine magnetic particles from liquids, slurries, gases, dry granular materials and powders for 80 years. We maintain 3 distinct lines of magnetic separators, including: Our Electromagnetic Separators utilize ...

The isodynamic separator's current is sensitive to the warming of the coils. Thus, a control of the electric current is needed. In the experiments done during this investigation the separation with the isodynamic separator was started, when the effect of warming was small (4 h of warming time).

The isodynamic separator consists of an electromagnet having long contour shaped two pole pieces with a long narrow air gap between them. The feed material to be separated is fed into one end of the magnetic field and allowed to travel through its entire length. The paramagnetic particles are influenced to move towards the narrow side of the …

The Frantz Isodynamic® Separator has a virtually unlimited useful life. The elements of the Magnetic Barrier Laboratory Separator were consequently designed so that all parts can be installed in the base and the magnetic circuit of any Isodynamic® Separator to convert it to a Barrier. (The first prototype of the Isodynamic® Separator ...

A superconducting isodynamic open gradient magnetic separator has been designed in order to test the separation of various slurries at high magnetic field. The system will be used as a measuring device in order to determine the conditions for the separation process at different applications. The magnet system consists of two racetrack coils. The separator …

To prove the comparability of directly measured and calculated curves, particle susceptibility distributions analyzed by an isodynamic magnetic separator are used. Based on calculated partition curves the cut susceptibility as well as the separation efficiency were extracted from the results of all experiments.

Ilmenite and rutile were separated using heavy liquids (bromoform and heated Thalium Clerici solution) and a Frantz Isodynamic Separator following the method outlined in Duchesne (1966). After the ...

The instrument used for the separations is the isodynamic magnetic separator Frantz. This instrument consists in a vibratory chute with variable slopes in vertical and horizontal directions. This chute is located between two electromagnets of adjustable current, which define the flux density of the magnetic field.

1.6.1.1. Set Up . Wipe down all areas around the Frantz and the nearby table with a damp paper towel to avoid contamination of your sample. Remove the cover over the Frantz, and wipe down any dusty areas of the machine with a slightly damp paper towel. Lay out a sheet of clean paper or foil on the table, and place 6 Dixie cups on this area.

Our approach emphasizes the key role of a stepwise use of a Frantz isodynamic separator to produce mineral separates of individual sulphide species that …

The following list (Table 1) and the accompanying chart (Fig. 1) of magnetic susceptibilities of minerals were compiled to fill the need for a guide in separating minerals in an isodynamic magnetic separator, and were especially designed for the occasional "do-it-yourself" user.

The result was the patented Barrier Separator (Model LB-1), which provides magnetic energy gradient/force on particles of a given susceptibility. By applying more than three times the force of the Isodynamic ® Separator, the Barrier Separator can separate minerals with much weaker susceptibilities. This specialized unit has allowed for:
