Ever increasing demand of coal in
sectors such as power & other metal manufacturing industries,
urbanization, increasing oil prices, increase in extracting capacity and
technological advancements are some of the major drivers for the global coal
washery industry. Additional cost associated with coal washery, composition of
raw feeds and absence of incentives schemes to the miner are some of the
factors restraining growth of this industry.

Almost half of the worlds energy
demand over the past decades was fulfilled by coal. In fact coal has been the
world’s fastest energy source driven by Asian demand and regional abundance of
fuel. Coal washery is an establishment where coal is alienated from slate and
different impurities through various mechanical processes which utilize water
and take gain of the difference in the specific gravity and its impurities of
coal. The more impurities or waste material is removed from the coal the
greater is the market value and lower ash content. Earlier coking coal was
only washed as it was used in steel manufacturing with an ash content of 17-18
% but new environment regulations has put restriction on high ash content coal
in power and other industries which necessitates the priority of washing non
coking coal also.
The segmentation of the market can
be done on the basis of Wet and Dry processes. In the initial stage crushing
is done to reduce the size of extracted coal and making it suitable for
washing. Size reduction technique involves various processes such as intact,
shearing, compression, splitting and attrition. After crushing screening
process is done for the separation of heterogeneous particle. Different types
of screens are used such as scalping screen, raw coal sizing screen, pre-wet
screen, heavy media recovery screen, desliming screen and dewatering screen.
Next process for cleaning of coal is through Jigs.
The method is operated on the basis
of difference in specific gravity. Jigs offer cost effective technology with
clean coal yield of 70-85%. Froth Floatation is the most widely used technique
for cleaning coal. It utilizes the difference in the surface characteristics
of coal and reuses it to clean ultra fine coal. The mixture of coal and water
is conditioned with chemical reagents so that air bubbles will stick on the
coal and floats on the top, while the reused particles sink. This cleaning
technique is generally expensive and complex and is majorly for metallurgical
coal. In launder process raw coal is fed into the high end of a trough with a
stream of water. As the mixture of water and coal flows down, particles with
the maximum settling speed settle down into the lower strata of the stream.
The dirt free coal particles settle into the upper strata before separation.
Some of the key players in the coal
washery market are Phil Group Coal Washeries, Larsen and Tubro Limited, China
Metallurgical Engineering & Project Corporation, CLI Corporation and
Adhunik Group among others.
