Coal - Structure and properties of coal | Britannica

Density differences make it possible to improve the quality of a coal by removing most of the rock matter and sulfide-rich fragments by means of heavy liquid separation (fragments with densities greater than about 1.5 megagrams per cubic metre settle out while the coal floats on top of the liquid).

Coal preparation plant - Wikipedia

A coal preparation plant (CPP; also known as a coal handling and preparation plant (CHPP), coal handling plant, prep plant, tipple or wash plant) is a facility that washes coal of soil and rock, crushes it into graded sized chunks (sorting), stockpiles grades preparing it for transport to market, and more often than not, also loads coal into rail cars, barges, or ships.

Light particles (coal) becomes fluidised with the assistance of autogenous medium (i.e., <6 mm material). The denser shale settles to the bottom, separating coal from middlings and rock. Fluidised coal is transported toward the front of the table and is discharged on the right-hand side. High-density material remains in contact with the table.

For good separation, the density difference between the heavy minerals and the light minerals in the feedstock should be at least 1 g/cm 3; and because the separation is dependent upon size and density, spiral separators are most effective at purifying ore if its particles are of uniform size and shape. A spiral separator may process a couple .

Heavy Media Separation Process

Heavy Media Separation Process

The heavy-media separation process, or HMS, employing ferrous media, usually ferrosilicon and/or magnetite, is the most generally used process for sink-float separations. A stable medium over the range of specific gravities from 1.25 to 3.40 can be maintained within close limits and is cleaned and recovered by magnetic means.

The Multotec SX10 low density spiral's reduced cut point of 1.55 g/cm3 delivers considerable advantages over the cut points of between 1.6 and 1.8 g/cm3 typically achieved in the coal industry today, according to Multotec Technology Manager, Faan Bornman. The result, he says, is cleaner coal with less waste being achieved in a single stage.
