Magnetic susceptibility of the minerals increases in the order: feldspars/nepheline syenite, eudialyte, arfvedsonite/aegirine. Therefore, the recovery of eudialyte by magnetic separation will require a two-stage process. Scoping tests were conducted on a Carpco high intensity magnetic
The mechanical separation aims to concentrate eudialyte through size reduction and magnetic separation to upgrade zirconium and its accompanying elements (Hf, Nb, Ta, and REE) into a eudialyte concentrate. • Magnetic separation will also enable the production of a nonmagnetic feldspar concentrate and a magnetic tailings product (arfvedsonite).
Jan 06, 2018 A combination of gravity and magnetic separation techniques were employed, resulting in limited success. The second part looked at the hydrometallurgical processing of eudialyte through various leaching experiments with sulfuric acid.

It is an old dressing technic for ore concentration. ... magnetic forces, buoyant forces, centrifugal forces, resistance to movement, or drag force. ... and biotite can be achieved by gravity separation. Separation of eudialyte and monzonite from gangue. Silica sand cleaning ...
Specific gravity: 2,74-3.10 g/ cm 3 Eudialyte is used as a minor ore of zirconium. Eudialyte typically has a significant content of U, Pb, Nb, Ta, Zr, Hf, and rare earth elements (REE). Eudialyte is found associated with other alkalic igneous minerals, in addition to the some minerals common to most igneous material in general.
The article presents data on separation of minerals of eudialyte ore with low magnetic susceptibility using a high-intensity wet magnetic separator and pulp pulsation. The optimal separator variables of the magnetic field inductance, pulp pulsation and matrix filler diameter to ensure maximum efficiency of processing are determined.

While magnetic separation and flotation were the focus of research, gravity, electrostatic and centrifuge methods were also applied, each of which achieved only poor eudialyte separation. Magnetic Separation Due to the paramagnetic behavior of eudialyte, magnetic separation
(a combination of gravity and magnetic separation), the authors of [26] studied hydrometallurgical processing of eudialyte Norra Kärr (Sweden) through various leaching experiments with sulfuric acid.
Gravity separation utilizes the heavier particles of the substance in question to settle-out faster after mixing and agitation. This is done often in water, in special graduated ‘sedimentation tubes’ or cylinders. Magnetic separation
Magnetic methods are more popular in mineral exploration than gravity, not least because magnetic data can be quickly recorded from the air and in conjunction with other geophysical surveys. Land gravity

The applicability of magnetic separation and direct selective flotation for the processing of eudialyte ore from Norra Kärr (Sweden) was tested. The eudialyte in the used sample contains around 4 % of REE. Magnetic separation is applicable for eudialyte ore processing. The higher the strength of the magnetic

Gravity separation and magnetic separation are mainly used to separate coarse-grained and medium-grained weakly magnetic iron ore (20~2 mm). During gravity separation, heavy medium or jigging methods are commonly used for the gravity separation
Magnetic separation takes advantage of the fact that magnetite is strongly magnetic (ferromagnetic), hematite is weakly magnetic (paramagnetic), and most gangue minerals are not magnetic (diamagnetic). A simple magnetic separation circuit can be seen in Figure 1.2.5 [9].A slurry passes by a magnetized drum; the magnetic
An otherwise unknown group of minerals, eudialyte is a zircon silicate consisting of rare earth oxides (REO), contained in a unique mineral structure and represented by a complex chemical formula.
Jul 01, 2014 The Nechalacho ore was processed using a combination of WHIMS and gravity pre-concentration using either a Knelson (80% – 53 μm feed) or a Falcon (80% – 44 μm feed) Concentrator to exploit the differences in specific gravity and magnetic properties of the different minerals in order to achieve separation.
