Currently, the wet coal beneficiation process is the predominant method for coal upgrading. The wet beneficiation processes include heavy media separation, cyclone (water only), froth flotation, and spiral separation [23,24]. The use of these technologies depends on the particle size of the feed and the quality of the product required.

The commercial processes of coal beneficiation are based on the differences in some physical properties of the pure coal and the impure coal (refuse). The difference in specific gravity is the basis for the largest number of coal beneficiation processes in which case they are termed as Gravity Concentration Processes.

Beneficiation includes crushing, grinding, gravity concentration and flotation concentration. Beneficiation is followed by processing activities such as smelting and refining. The beneficiation process begins with milling, which is followed by flotation for further beneficiation.

The first segment of the coal beneficiation process involves feeding the ore through a roll crusher and then sizing screen. Following sizing, the coarser coal is fed to a DMS drum via an over belt magnet, which eliminates any ferromagnetic contaminants, such as old bolts, tool shards, and other metallic scraps.

Coal Beneficiation Coal beneficiation is a process by which the quality of raw coal is improved by either reducing the extraneous matter that gets extracted along with the mined coal or reducing the associated ash or both. Two basic processes of beneficiation: Dry-deshaling: Non-coal or shaly-coal is removed without using any liquid media.

Those processes using water as medium are WET processes and are known as Washing Processes. The coal beneficiation plants using wet processes are named as Coal washeries. For raw coal fines of –0.5 mm, the difference in surface property is utilized since conventional gravity dependent processes are inefficient for this size range.

Beneficiation. In the mining industry or extractive metallurgy, beneficiation is any process that improves (benefits) the economic value of the ore by removing the gangue minerals, which results in a higher grade product ( ore concentrate) and a waste stream ( tailings ).
