Magnetite-coal separation by continuous HGMS

2021-2-11  @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 the coal

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.

magnetic separation chemistry,magnetic seperation

The Magnetic Separator is suitable for wet magnetic separation of materials,such as magnetite, calcined ore, etc., and it can remove the iron in the coal, non-metal and construction industries. The magnetic system is made from high quality ferrite magnetic materials and /or rare earth magnet steel. On the shell surface, the magnet intensity is 100-600mt.

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.

Enhanced magnetic separation of pyrite from coal

Abstract: The objective of this research was to improve the magnetic separation of coal and pyrite by enhancing the magnetic susceptibility of pyrite in run-of-mine 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 form. Studies included the measurement of the dielectric

Magnetic separation of coal fly ash from Bulgarian

2019-11-3  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.

Magnetic Separation an overview ScienceDirect

Carrier magnetic separation has been proposed for more effective separation of water and solids from acid mine water to generate very pure water (Feng et al., 2000).As discussed in Chapter 10, dissolved heavy metals like zinc and copper can be recovered from acid mine drainage (AMD) by selective precipitation controlling the pH for the precipitation of specific metals.

Entrainment of Magnetite by Coal During Dense

2018-6-6  Although most of the magnetite used in dense-medium coal beneficiation can be recovered by magnetic separation, there are small but significant losses. The magnetite losses can be attributed to removal in the wash wastes or uptake into fractures of the coal particles.
