The hard coal beneficiation process in mechanical preparation plants generates coarse, small or fines rejects and coal tailings slurries. The tailings are the finest grain size, with the majority below ~ 0.25 mm, whereby material sized below 0.035 mm makes up to 60% share in the slurry composition.
Opportunities for fine coal utilisation 7 A considerable proportion of material extracted during coal mining is rejected. This includes material that is largely a by-product of coal processing, having significant energy content and small particle sizes including substantial amounts below 0.15 mm. Such fine coal is difficult to handle and poses

cleaner coal unsuitable for the Lurgi gasifiers. Hence, methods need to be evaluated which can beneficiate the coarser fractions of the coal, without reduction to fine sizes (smaller than 5 mm). 6.1 Coal Beneficiation Technology Options For the beneficiation of coarse coal (larger than 5-6 mm), there are basically two wet
A theory of the dry separation of coal by density difference is proposed. The mechanism and efficiency of separation of coal particles in an air dense medium fluidized bed (ADMFB) according to bed density and the density distribution in the fluidized bed is studied. The results show that the uniform and stable fluidized bed can be formed at specific conditions.

In the anthracite region, culm consists of coarse rock fragments containing as much as 30 percent small-sized coal. Silt is a mixture of very fine coal particles (approximately 40 percent) and rock dust that has settled out from waste water from the plants. The terms culm and silt are sometimes used interchangeably and are sometimes called refuse.
