The fluid conditions that best facilitate the separation of magnetic particles are low oil viscosity (iso vg 32 vs. iso vg 320 for instance) and low oil flow rate (2 gpm vs. 50 gpm). even extremely small, one-micron particles can be separated from the oil if both of these fluid conditions exist concurrently.

60585 fischer tropsch (f-t) synthesis is a promising process for producing high quality, environmentally clean, diesel fuels. however, the separation of catalyst fines from the fischer-tropsch (f-t) reactor product stream has been a major impediment to applying the technology for the conversion of hydrocarbon resources such as coal and petroleum coke to clean burning .
a nanomagnetic separation method based on diethylenetriaminepentaacetic acid (dtpa) conjugated with magnetic nanoparticles (mnps) is studied for application in spent nuclear fuel separation. the high affinity of dtpa towards actinides aids in separation from the highly acidic medium of nuclear waste.
Magnetic separation takes advantage of differences in the magnetic properties of minerals. minerals fall into one of three magnetic properties: ferromagnetic, paramagnetic and diamagnetic. ferromagnetic minerals are themselves magnetic (i.e., magnetite and pyrrhotite) and can be easily separated from other minerals with a magnet since they will .
@article{osti_5816067, title = {magnetite-coal separation by continuous hgms}, author = {dobby, g s and kelland, d r}, abstractnote = {magnetite, slurried in water, is used to create an apparent heavy medium in which fine coal (0.1 to 2.4 mm) is cleaned of its mineral impurities. the magnetite is much finer in size (1 to 44 ..mu..m) than the coal and is usually recovered from .
Burning the fuel is concentrated by separating metals that can be separated by physical methods, we will use the magnetic separation method to separate the iron in the ash. the wet magnetic separation process was carried out for the iron present in the ashes resulting from burning the fuel and is present in the form of magnetite. the device.

Magnetic separation is one of the most common and important physical separation techniques. magnetic separation is which separating components of mixtures by using magnets to attract magnetic materials or magnetically susceptible particles or bodies are separated from non-magnetic particles.
magnetic material followed the belt around the magnetic drum, after which it could be collected in a separate bin under the apparatus. thereby, a magnetic separation was achieved. download : download high-res image (73kb) download : download full-size image; fig. 2. illustration of the magnetic separation procedure used at kraftringen.
magnetic separation method. magnetic separation is a process used to separate materials from those that are less or non magnetic. all materials have a response when placed in a magnetic field, although with most, the effect is too slight to be detected. the few materials that are strongly affected (magnetised) by magnetic fields are known as .
The results show that we could obtain concentrated iron ore grade of pine roasting and magnetic separation grade of iron concentrate 61.64% with the recovery of 79.75% via pine fuel roasting, 61.75% with the recovery 80.16% via rice chaff, and 61.47% with the .

magnetic separation may be used for coal beneficiation when the gangue minerals contain such iron phases, however their very weak magnetic susceptibilities would require strong magnetic field strength (dwari and rao, 2009). previous works on the magnetic separation of pyrite from coal have shown pyrite to be a weakly paramagnetic mineral.
