Eudialyte Magnetic Separation Recovery - 911 Metallurgist

2018-4-28  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 separator

Eudialyte - an overview ScienceDirect Topics

Eudialyte can be concentrated by crushing and milling followed by dry, high-intensity magnetic separation. This leads to separation from the other two main minerals, feldspar and arfvedsonite. Use of these two products is also evaluated and will result in minimal waste material.

An Overview of Beneficiation and Hydrometallurgical ...

2019-9-9  Previous experiments on the eudialyte group minerals have indicated that a multi-step process is necessary for the separation of the eudialyte from its gangue components. Recently, Vaccarezza and Anderson investigated a two-stage process via gravity and magnetic separation for the Norra Kärr eudialyte

2018-5-22  Different size fractions were studied for liberation purposes. This gravity separation step was implemented for the removal of the heavy iron-bearing mineral aegirine. This float product is then processed in a wet high-intensity magnetic separation (WHIMS) at 1 Tesla to separate the paramagnetic eudialyte from the non-magnetic gangue minerals. The implementation of this process resulted in limited success for a clear separation of eudialyte

TASMAN ADVANCES MINERAL PROCESSING AT NORRA

2012-11-8  Due to the paramagnetic behavior of eudialyte, magnetic separation performed very well under non-optimized conditions. Numerous tests were completed which demonstrated the excellent magnetic extractability of both eudialyte and a common iron-bearing mineral aegirine. Review of external publications suggest aegirine is not soluble under the acid conditions considered for hydrometallurgical processing of Norra Karr ore, and shall therefore be inert in a REE-leach circuit. Example recoveries achieved with single pass (not re-circulated) WHIMS (wet high intensity magnetic separation)

2014-7-1  The magnetic force on a particle in a magnetic separator may be controlled by varying the magnetic susceptibility of the particle/medium, the applied magnetic field or the magnetic field gradient. The size range at which magnetic separation is effective depends on which of the three main forces on a particle (gravitational, magnetic and fluid drag) is dominant at a particular size ( Oberteuffer, 1974 ).

Magnetic-gravity separation of iron ore

2016-7-20  The essence of magnetic-gravity separation (MGS) is that, by applying electromagnetic field having the intensity H=4 to 16 kAlm and inhomogeneity gradient up to 4 kAlm2 per meter of suspension, in required hydrodynamic regime, the ferromagnetic particles, as a result of the effect of magnetic and gravity forces, pass into the lower

2012-11-8  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 performed very well under non-optimized conditions.
