Enhanced magnetic separation of pyrite from coal after. Abstract The objective of this research was to improve the magnetic separation of coal and pyrite by enhancing the magnetic susceptibility of pyrite in runofmine coal through the use of selective dielectric heating Separation of pyrite from coal would be facilitated by changing a portion of each pyrite particle to a more magnetic …
Magnetic Separation - an overview | …
Magnetic separation has some limitations. It cannot separate iron and steel from nickel and magnetic stainless steels. Also, composite parts containing iron will be collected which could contaminate the melt. Hand sorting may be used in conjunction with magnetic separation to avoid these occurrences.

Magnetic Separation in the Mining Industry - …
Magnetic separation machines consist of a vibratory feeding mechanism, an upper and lower belt and a magnet. The bulk material is fed through the vibrating mechanism onto the lower belt. At this point, the magnet pulls any material susceptible to magnetic attraction onto the upper belt, effectively separating the unwanted metals from the rest of the bulk.
Using microwave pretreatment to improve the …
The different magnetic properties of different components in the coal (e.g., the inverse magnetic properties of the coal and the paramagnetic properties of coal-measure pyrite and some of its ash minerals) can be exploited through the use of high-gradient magnetic separation techniques.

Fine Coal Desulfurization by Magnetic …
Pyrite in fine coal was heated selectively by microwave energy to strengthen its magnetism in this study. Then, the inorganic sulfur in fine coal (−0.5 mm) was removed using a 2 T strong magnetic roller magnetic separator. The migrating regulation of organic sulfur-containing groups and harmful elements was analyzed by employing a microwave energy-intensive process.
Magnetite and Carbon Extraction from Coal Fly …
In this study, enrichment methods for coal fly ash (CFA) from Omsk thermal power station No. 4 (TPS-4) were investigated. The magnetite and unburned carbon concentrates were obtained by magnetic separation and flotation methods. The wet magnetic separation used in the study increased the magnetite content in the magnetic fraction from 10.48 to 12.72 wt % compared to dry magnetic separation.
