S.G. Frantz Co. Inc., a pioneer in the development of magnetic separators since 1935, has a long-standing commitment to providing quality systems for the most diverse industrial applications. Its units have been widely used in geological and mineralogical facilities worldwide, improving separation quality, providing better particle feed and travel …
Frantz Magnetic Separator¶ NOTE: It is important during all steps to avoid touching the separating tray with your fingers. Oils from your fingers could make grains stick to the tray and be detrimental to proper separation. Wipe down all areas around the Frantz and the nearby table with a damp paper towel to avoid contamination of your sample.
We offer four different permanent magnet separators, ranging from PQ3 (approximately twice the size of an automobile oil filter) to the PQ6 (our largest permanent magnet separator, with a capacity of 10 times that of the PQ3). Whatever your needs, S.G. Frantz has the expertise to help you find the right separation solution.
The Frantz Canister Separator (Model L-1CN) is a benchtop unit designed for high-gradient, high-intensity magnetic separation of fine liquid suspended particles (including nanoparticles).
A significant increase in the magnetic field gradient can be achieved by placing ferromagnetic bodies (such as balls, mesh or steel wool) into the magnetic field of a separator (Frantz, 1937).These bodies (usually called a matrix), generate, when magnetised, a high local field gradient of the magnitude as high as 5 × 10 4 T/m. This …
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. …
Frantz isodynamic. Based on your result, it is quite confusing to the reader again if Ring-type magnetic separator was conducted before Frantz isodynamic separator or the author conducted these two methods and made a comparison between these two methods as in subsection 3.4. Magnetic Separation. In addition, Figure 1 is not clearly …
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.
A DISCUSSION OF MAGNETIC SEPARATION TECHNIQUES 197 Introduction Minerals separation based on magnetic susceptibility differences in particles is accomplished wet or dry, at various intensities and in different basic machine configurations. The following types of industrial magnetic separators can be found in a modern mineral sands plant:
The commonly used methods for mineral enrichment are density separation using heavy liquids such as sodium polytungstate (SPT), lithium heteropolytungstate (LST) or lithium …
High intensity dry magnetic separators are gaining popularity for the separation of para-magnetic minerals due to the cost economic factor. Induced roll magnetic separator is found to be an effective dry separator for the separation of fine particles. Separation efficiency of this separator depends on mineral characteristics …
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 …
Frantz Magnetic Separator. The heaviest fraction will then undergo separation by magnetic susceptibility using the Frantz magnetic separator. By adjusting the power of …
The rinsed and dried samples were passed through a Frantz magnetic separator [64] to remove heavy minerals and most feldspars. Subsequently, the samples were soaked for 1 hour in 30% H 2 O 2 at 50 ...
high efficient magnetic separator used in mineral separation. Use of magnetic separation for purifying quartz for luminescence. preferred protocol for dating quartz calls for efficient methods for techniques used for mineral separation, and in the past it was separators are stable and the results reproducible.
Assemble the Frantz by sliding the separating tray between the magnets, and then screwing in the two bolts to hold it in place. Then attach the separating tube apparatus …
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. Diamagnetic and paramagnetic minerals are separated via …

AbstractTheory and practice are described for a new processing method capable of precise mineral separations based primarily on differences in particle specific gravities at specific gravity split points from 1.5 to 21.0 and beyond. Separations are analogous to those achieved using rotating heavy media, except that the effective …

This book treats magnetic separation from the point of view of both the engineer in the field who operates magnetic separators and the research scientist in the laboratory. It emphasizes those aspects of magnetic separation where lack of support in fundamental research is most evident. The intention is to bring the engineer and the scientist closer …
The Reading Rare Earth Magnetic Drum (RED) uses a unique 5 pole magnetic element to generate a field intensity in excess of 0.7 Tesla on the drum skin. The magnetic element design affords the maximum field gradient and the 5 poles enables additional cleaning of the magnetic stream. This gives a very selective separation at high throughputs …
