Coal processing through jigs also rests on pure economic considerations. Recently Coal India Ltd. revised the prices for grade C and medium coking coals that will have severe impact on the industry. It is estimated that in the power and steel sectors the increase would be of the order of Rupees 25 and 10 crores respectively.

3.2.2 Design Consideration in Jigs (a) The main frame of jig must be strong enough so that the deflection of jig is as minimum as possible. This deflection of jig is caused due to the forces of cutting, clamping of the workpiece or clamping to the machine table. The mainframe of the jig should have the mass to prevent vibration and chatter.

The clean coal ash data obtained in these experiments were in the range 20.4-23.5%. It may be noted that the feed coal contained 27.5% ash. Thus, reduction of ash in a single pass was quite significant. However, more significant variation in the mass yield of the clean coal (51.5-83.4%) under the test conditions was observed.

Coal is abundant and inexpensive. Assuming that current rates of usage and production do not change, estimates of reserves indicate that enough coal remains to last more than 200 years. There are, however, a variety of problems associated with the use of coal. Mining operations are hazardous. Each year hundreds of coal miners lose their lives or are seriously injured.

Fine coals are dewatered in an energy efficient process in which a non-polar liquid or a mixture of different hydrophobic liquids are used to displace the water from the coal surface. This process works with higher rank coals that are naturally hydrophobic so that the coal surface from which the water is displaced has a stronger affinity for the hydrophobic liquid than the water.

results showing the effects of drum rotational speed on processing of coking coal fines are shown in Fig.5. As it can be seen with an increase in drum speed from 240 to 280 rpm at 25% pulp density, a better clean coal can be produced. At 280 rpm a clean coal having 16.43% ash with 47.3% recovery can be achieved from a feed of 33.25 % ash.
