The alternative route yielded significant gains in weight and metallurgical recoveries, reaching values 3.3 and 4.4 higher ...
Permanent magnets or electromagnets generate a non-homogeneous magnetic field in the separation gap. The desired pattern of the magnetic field is achieved by shaping the pole tips. A separation chamber placed between the pole-pieces of the magnetic circuit is filled with a magnetic fluid. FIGURE 1 The concept of separation with magnetic fluids.

Magnetite and other strongly magnetic heavy minerals were removed from the heavy-mineral fraction by use of a hand magnet. The remaining sample was passed through a Frantz Isodynamic Separator and a nonmagnetic fraction was examined for its mineralogical content with the aid of a binocular microscope and an x-ray diffractometer.
Ending on extraction of selected minerals from the rocks light, heavy, accessory, magnetic, non-magnetic and paramagnetic using Frantz isodynamic magnetic separator. Magnetic separation on Frantz is arguably the most essential method for bulk heavy mineral concentration induced magnetic fields at various electric current settings.

isodynamic magnetic separator, and so a pestle and mortar was required which was harder than anorthite hardness of 6 on the Mohs Scale, yet not so hard as to grind a significant amount of sample down to 75 m. For this reason, an agate pestle and mortar was chosen as it satisfied both these requirements, having a
Jun 04, 1998 Particle separation in a magnetic colloidal fluid with a susceptibility gradient created by means of a FrantzIsodynamic magnet is described. The positions where particles and fluid are in equilibrium are a function of the particle magnetic susceptibility only. This method allows magnetic separation of several materials with a wide range of magnetic susceptibilities in a single separator ...
