Wet, high intensity magnetic separators (WHIMS) generate high field strengths and pass slurry through matrix arrangements to collect the magnetic fraction. WHIMS are …
Fingerprint Dive into the research topics of 'Maceral and pyrite partitioning through high-gradient magnetic separation of selected western kentucky coals'.
A recycling process of iron from red mud by magnetic separation is proposed, in which iron oxide (Fe2O3) in red mud transforms to magnetite (Fe3O4) by anaerobic co-roasting with pyrite (FeS2).
The basic principle involved in high gradient magnetic separation (HGMS) lies in coal being diamagnetic (repulsed by a magnet) while pyrite is paramagnetic …
The effects of microwave treatment on the floatabilities and magnetic susceptibilities of some sulfide minerals, namely, pyrite, chalcopyrite, galena and sphalerite, were studied. Pure mineral samples were prepared in -425+212-μm, -212+106-μm and -106+38-μm size fractions. Microflotation and magnetic separation tests were …
The research on the combined use of magnetic separation and flotation to treat pyrolysis slag under different grinding fineness was explored, using two processes: first magnetic separation followed by flotation (Fig. 9 a) and first flotation followed by magnetic separation (Fig. 9 b). Flotation uses sodium humate as pyrite inhibitor and ...
Results showed that, at the optimum separation conditions, i.e., 10 l/h feeding rate, 5% pulp density, 2200 Gauss, and 0.6% canister loading, a coal concentrate assaying …
This chapter introduces the principle of how low-grade iron ores are upgraded to high-quality iron ore concentrates by magnetic separation. Magnetite is the most magnetic of all the naturally occurring minerals on earth, so low-intensity magnetic separators are used to upgrade magnetite ores.
Pulsating high gradient magnetic separation (PHGMS) was innovatively used to upgrade an unqualified pyrite concentrate with arsenic content reaching as high as 3.49%.
Pyrite is separated from other minerals mainly by flotation. However, the hydrophilicity of pyrite is affected by many factors, causing it to easily enter the concentrate and consequently reduce the quality of concentrate. Highly efficient pyrite depressants can be selectively adsorbed on the surface of pyrite to improve its hydrophilicity, thereby …
The magnetic strengthening process with microwave energy of fine coal was studied using a variety of methods: magnetic strengthening of fine coal, electromagnetic response characteristics of coal pyrite, energy storage concept, magnetic strengthening mechanism of pyrite under the microwave effect, and inorganic mineral …
Removal of Iron from Pyrite-Rich Coal Refuse by Calcination and Magnetic Separation for Hydrometallurgical Extraction of Rare Earth Elements
Pyrite cinder (PyC) is an iron-enriched tailing.Suspension magnetization roasting(SMR) technology can convert hematite into magnetite, the magnetic properties of the product have been improved, and then through the magnetic separation to complete the separation of magnetite and gangue. SMR consumes less energy than the direct …
Pulsating high gradient magnetic separation (PHGMS) was innovatively used to upgrade an unqualified pyrite concentrate with arsenic content reaching as high …
A recycling process of iron from red mud by magnetic separation is proposed, in which iron oxide (Fe 2 O 3) in red mud transforms to magnetite (Fe 3 O 4) by anaerobic co-roasting with pyrite (FeS 2).TG-DTA and XRD results showed that hematite was reduced to magnetite by the thermo-decomposed compounds (iron monosulfide, …
Wet high gradient magnetic separation WHGMS of an Egyptian coal sample was carried out to minimize its pyritic sulfur content reaching 1.60% (2.9% total sulfur). Optimization of the process...
Pyrite is commonly referred to as "fool's gold."Although much lighter than gold, its brassy color and relatively high density misled many novice prospectors.

Recovery of iron from pyrite cinder by suspension magnetization roasting-magnetic separation method: Process optimization and mechanism study
This study presents a new technique that uses high-temperature chloridizing -reduction-magnetic separation to recover iron from pyrite cinder containing non-ferrous metals.
The porosity of pyrite cinder mixture is high, which is in favor of reduction. The pyrite cinder mixture ... and magnetic separation. Firstly, the pyrite cinder mixture and sodium sulfate solution were mixed and compacted into briquettes (U10 9 15 mm) with pressure of 10 MPa. Then, the bri-quettes were dried in the oven at 105 C for 4 h.
Although the magnetic difference between pyrite and coal is small, it is still large enough that with appropriately designed high-intensity magnetic separators that they can be …
A high-intensity magnetic separator was used for the separation of fine coal, and an effective way to achieve the clean utilization of pulverized coal before its combustion was investigated.
MineralMate is a standalone MATLAB-based program designed to optimize the workflow associated with the magnetic separation of minerals. For nearly every bulk geochemical analysis some amount of mineral separation must occur, and the use of an electromagnetic separator is ubiquitous and considered as standard practice in many …
