In broader terms, mineral processing consists of two functions. Firstly, it involves the preparation and liberation, of the valuable minerals from waste minerals and secondly, the separation these values into two or more products, called concentrates. The term separation in this case is synonymous with concentration.

During the hard coal beneficiation process, coal tailing slurries and coarse, small, or fine rejects generate in mechanical preparation plants. The finest grain size is observed in the tailings, with the majority below ~0.25 mm, where particles sized below 0.035 mm constitute a 60% share in the slurry composition.

In the process developed by the Central Fuel Research Institute of India, coal slurry is treated with diesel oil (2% additions) in mills and then agglomerated with 8–12% additions of heavy oil. It is known that low rank and/or oxidized coals are not a suitable feedstock for beneficiation by the oil agglomeration method.

(up to 25% reduction). Coal beneficiation is based on wet physical processes such as gravity separation and flotation. Beneficiation produces two waste streams: fine materials that are discharged as a slurry to a tailings impoundment, and coarse material (typically greater than 0.5 millimeters (mm) that is hauled away as a solid waste.

Sieve bends are used in coal preparation plants to confiscate the ultra-fine coal and drain the dense media cyclone products. These screens can handle a high throughput of coal slurry without blinding the apertures. The overflow product from the sieve bends mostly consists of water and a considerable amount of undersized material.
