Magnetic separation of rare-earth ions: Transport processes and pattern formation Zhe Lei, Barbara Fritzsche, and Kerstin Eckert Phys. Rev. Fluids 6, L021901 – …

The applied magnetic intensity was increased from 0.4 T to 1.4 T. After recovering magnetic products at 0.4 T, the remaining non-magnetic sample was fed into a magnetic separator that was adjusted to a 0.2 T higher magnetic intensity for further separation. The magnetic separation tests were carried out

Flotation-magnetic (FM) separation is a newly-developed technology for the economic recovery of rare earth elements from the Dalucao ore. The FM process selectively agglomerates the rare earth particles while separating them from gangue minerals by bubble flotation. The agglomeration of fine bastnaesite particles has been observed by optical ...

This work bridges two gaps in the magnetic separation of rare-earth ions. (1) A material property database is provided for the solutal expansion coefficient and the magnetic susceptibility of 11 out of 17 trivalent rare-earths. (2) A novel protocol is developed to enhance and resolve the magnetic term of the Kelvin force. For that purpose, an assembly of partition …

The behavior of iron and rare earth in magnetic separation was found to be controlled by the particle size after grinding. Using ball milling, 98.2% of rare earth and 96.7% of Fe were separated. A hydrochloric acid solution with a low concentration of 3 mol/L was used to leach rare earth from the magnetic separation tailings.

The yttrium-- rare earth concentrates were obtained from Fergusonite ore, Gadolinite ore, and a by-product from an ion-exchange resin separation process. In each case the mixture in terms of oxide was composed of from 50 to 60% yttrium and 5 to 15% heavy rare earths with the light rare earth fraction constituting the remaining material.

Different magnet materials have different properties, so the choice is very important. The latest high intensity magnetic separators use Neodymium (NdFeB) (also known as Rare Earth) magnets. This is the strongest magnet material and is effective in extracting the finest ferrous and paramagnetic particles.

We anticipate that with proper pretreatment, mainly consisting of size reduction, a permanent magnet roll separator will be the method of choice for recovery of rare-earth oxides. While magnetic separation cannot extract diamagnetic products (such as La 2 O 3) from the soils, we expect that over 90% of paramagnetic rare earth oxide components ...

Whilst separation techniques relying on gravitational forces have become relatively sophisticated in their application to biology the same is not true for magnetic separation procedures. The use of the latter has been limited to the few cells which contain …

A process for the separation of rare-earth elements has been developed which is enhanced by the presence of an external magnetic field. Abstract. The separation of rare-earth ions from one another is challenging due to their chemical and physical similarities. Nearly all rare-earth separations rely upon small changes in ionic radii to direct ...

Abstract— The use of magnetic fields in nonaqueous spent nuclear fuel treatment processes involving molten salts opens up new possibilities for selective extraction of radionuclides. In this research, this approach has been applied to the selective extraction of rare-earth elements and zirconium. We have studied strontium hexaferrite and a spinel ferrite as a …

This creates a distinct advantage to using rare-earth dry magnetic separators: the ability to produce a variety of TiO 2 products rather than a simple mag/non-mag split. Additionally, rare-earth dry magnetic separation circuits are typically lower in capital and ongoing maintenance costs, and are less complicated to operate than WHIMS.

The magnet lifts the magnetic minerals and puts across the field leaving the gangue to tailing. The system is widely used in mineral beach sand industry for separation of ilmenite and rutile. However, it is replaced by rare earth role magnetic and rare earth drum magnetic separators.

Magnetic separation is an emerging technology that uses magnetism for the efficient separation of micrometre-sized para- and ferromagnetic particles from chemical or biological suspensions. Enrichment of low-grade iron ore, removal of ferromagnetic impurities from large volumes of boiler water in both conventional and nuclear power plants, or ...

The high density product recovered from the non-magnetic product was conducted in the third magnetic separation process to recover the remaining rare-earth minerals. As a result, zircon could be recovered as a non-magnetic product in the third magnetic separation process, at a 2.1% yield, 42.8% grade, and 77.2% recovery.

The stability criterion for the magnetic separation of rare-earth ions is studied, taking dysprosium Dy(iii) ions as an example. Emphasis is placed on quantifying the factors that limit the desired high enrichment. During magnetic separation, a layer enriched in Dy(iii) ions is generated via the surface evaporation of an aqueous solution which is levitated by the Kelvin force.
