Heavy Minerals and Magnetic Separation

2007-12-28  The simplest form of magnetic separation is by hand magnet, a procedure which works for only one common mineral - magnetite. Other minerals having magnetic susceptibility are separated by using an apparatus that can generate strong electromagnetic fields. The Frantz separator (Fig. 1) incorporates an electromagnet with

Ugrandite Garnets: Andradite Uvarovite

Ugrandites are referred to as the calcium Garnets. All 3 gem species (Uvarovite, Grossular and Andradite) have calcium in the A site of their chemical formulas. Like Pyralspites, they exhibit a wide diversity of color, particularly among Grossular Garnets. Small amounts of chromium from Uvarovite Knorringite, and vanadium from Goldmanite, are ...

Ferrimagnetic - an overview ScienceDirect Topics

In a ferrimagnetic garnet, the magnetic moments of the octahedral and tetrahedral sublattices are antiparallel to each other. The moments of the Gd 3+ and heavier R 3+ ions couple antiferromagnetically to the net moment of the Fe 3+ sublattices. The resulting magnetization of the garnet is the sum of these three contributions:

High Power Ferromagnetic Resonance at X-Band in ...

2021-12-30  Resonance experiments have been performed at X-band on spherical samples of polycrystalline yttrium garnet, yttrium-gadolinium garnet, yttrium-holmium garnet and nickel-cobalt ferrite. The RF field strength extended up to 60 Oersted. In the case of yttrium garnet the samples differed considerably in density and hence in Iinewidth. At fairly low power levels the

2007-9-1  The susceptibility of Dy 3 Te 2 Li 3 O 12 also exhibits an antiferromagnetic ordering feature at approximately 2 K, reminiscent of that in dysprosium aluminum garnet at T N =2.53 K . Although the lattice constant of Dy 3 Te 2 Li 3 O 12 is much closer to that of Dy gallium garnet, its magnetic properties resemble Dy aluminum garnet more closely.
