A laboratory size High Gradient Magnetic Separator (HGMS) system capable of producing fields of 2.2 Tesla was used to separate the iron containing magnetic fraction from coal fly ashes.
The single float-sink test defines the relative amount of float-product and sink-reject that should result from the coal being washed in that preparation plant. The second type of float-sink analysis tests a coal sample in a succession of density baths to determine the optimal density for separation of the coal from rocks and minerals.

What Is Coal Preparation? • Coal preparation is the removal of undesirable material from the Run-of-Mine (ROM) coal by employing separation processes which are able to differentiate between the physical and surface properties of the coal and the impurities. Through coal preparation, a uniform product is achieved.
----- ABSTRACT A research program at the Francis Bitter National Magnet Laboratory has de- monstrated successful recovery of magnetite from mixtures of magnetite and coal — like those found in a coal-washing circuit — by High Gradient Magnetic Separation.

A laboratory scale procedure for separation of the maceral constituents of coal has been developed. This procedure is a modification and scale-up of our earlier density gradient centrifugation method. The technique enables us to separate larger quantities and to obtain higher density resolutions of ...
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.
