An open-gradient drum magnetic separator with a superconducting magnet system has been operating commercially since the 1980s (Unkelbach and Kellerwessel, 1985; Wasmuth and Unkelbach, 1991). Although separation is identical to that in conventional drum separators, the magnetic flux density at the drum surface can reach over 4 T.

Effective processing of low-grade iron ore through separation techniques 569 found that high intensity magnetic separator tests were limited to very close range of sizes between 2 and 0.125 mm. The final magnetic product assayed 61% Fe at an iron recovery of 90.3%. However, 5% by weight was obtained as middling assaying
Nov 05, 2016· Vertical Ring Pulsating High Gradient Magnetic Separator (VPHGMS) The magnetic separator used in this research study is a newly (2008) designed wet high intensity Magnetic separator called Longi LGS 500 and is shown in Figure 1. The said separator has a capability to attract materials with weakly magnetic attributes .
Mar 15, 2019· 2.3. Frantz isodynamic magnetic separator. In the present work, Frantz isodynamic magnetic separator (Model L-1, S.G. Frantz Co. Inc., U.S.) was used to study the magnetic properties of the hematite ore before and after heat treatment. The instrument is generally used to characterize the magnetic properties of the ore minerals.
The test results so far have shown clearly that it was possible to recover usable quality magnetic concentrates from both particle size fractions is far as the iron percentage was concerned. The non-magnetics from the cross-belt, magnetic separator containing hematite and limonite (approximately 38 Fe) were treated by Permroll.

The use of hematite magnetic separator: dry permanent magnet roller type strong magnetic field high gradient magnetic separator is a special beneficiation equipment for hematite. The magnetic field strength of the equipment is up to 14500Gs, the magnetic field gradient is large, the electricity consumption is small, and the performance is stable. .
In Figure 9.12, SLon magnetic separators are used for processing a specularite ore containing about 35% Fe. The run-of-mine ore is mainly composed of specularite and quartz. The ore is first ground down to about 85% -75 μm using ball mills. SLon magnetic separators are then used for roughing and cleaning to extract the specularite particles.
Introduction magnetic separator varies with the minerals to be sepa- rated, field intensity and field gradient used, for instance, In a magnetic separation system, the force on a par- about 10–20 lm for hematite if a Jones high-intensity ticle toward increasing field intensity (F) is expressed by magnetic separator is used.

The bigger the flocs, the higher is the separation efficiency. This suggests that the high efficiency of the FMS process might be due to the considerable increase of magnetic force on hematite fines in a magnetic field because of the formation of hydrophobic flocs, leading the fines to be held on the separation plates in a magnetic separator.

Nov 10, 2006· Magnetic batch separation of 16-nm water-soluble Fe 3 O 4 NCs with a conventional separator (Dexter Magnetic LifeSep 50SX). The field gradient at full field was 23.3 T/m. (A) Appearance of the solution immediately after placement in the separator.
This finding suggests that the high efficiency achieved by the FMS process might be attributed to the considerable increase of the magnetic force on the iron mineral fines in the form of hydrophobic flocs in a magnetic field, thus the fines can be held by the separation plates in a magnetic separator and then be collected as magnetic concentrates.
Jan 31, 2018· Magnetite contains iron in the form of Fe 3 O 4. Hematite contains iron in the form of Fe 2 O 3. ... Magnetite can be separated from a mixture using low-intensity magnetic separators. Hematite: ... The main difference between magnetite and hematite is that magnetite is ferromagnetic whereas hematite is paramagnetic.
In recent years, with the development of technology, magnetic material and non-magnetic material are separated by high gradient magnetic separator. After separation, Fe content of 20% of the mud can be increased more than 56% for reuse; extracted non-magnetic substances are available to produce cement, brick, road filler material.
