Magnetic separation of coal fly ash from Bulgarian power ...

Fly ash from three coal-burning power plants in Bulgaria: 'Maritza 3', 'Republika' and 'Rousse East' were subjected to wet low-intensity magnetic separation. The tests were performed at different combinations of magnetic field intensity, flow velocity and diameter of matrix elements. It was found that all parameters investigated affected the separation efficiency, but their influence was ...

Coal Washing, Magnetic Separation Processing

The dense medium separation process used in most coal washing and magnetic separation plants requires a suspension of finely milled magnetite in water. Magnetite for coal washing must be of overall high purity and be devoid of contaminants, such as hematite, sulphides or other minerals. Magnetite is reasonably durable (and therefore does not readily break down), and is chemically stable during ...

Magnetic Separator - an overview ScienceDirect Topics

IEA Coal Research, in The Problems of Sulphur, 1989. High gradient magnetic separation (HGMS) Conventional magnetic separators are largely confined to the separation or filtration of relatively large particles of strongly magnetic materials. They employ a single surface for separation or collection of magnetic particles.

Magnetite and Carbon Extraction from Coal Fly Ash

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.

Enhanced magnetic separation of pyrite from coal after ...

Separation of pyrite from coal would be facilitated by changing a portion of each pyrite particle to a more magnetic form. Studies included the measurement of the dielectric properties of different coal fractions at frequencies ranging from 1 MHz to 12 GHz. These values were then used to calculate the theoretical heating expected in these materials and their mixtures at 2.45 GHz. The ...
