Coal is the primary source of energy for most of the countries in the world. Although the main use of coal is in the generation of electricity recently synthesis of liquid fuel from coal is becoming attractive although coal liquefaction is a very old and well known process that was developed just after World War I.

What Is Coal Preparation Energy.gov

 · What Is Coal Preparation • Coal preparation is the removal of undesirable material from the Run-of-Mine (ROM) coal by employing separation processes which are able to differentiate between the physical and surface properties of the coal and the impurities. Through coal preparation a uniform product is achieved.

Jigging Article about Jigging by The Free Dictionary

Jigging is a particularly suitable economical method for extracting minerals in coarse inclusions which do not require crushing to a small particle size from coals and certain ferrous-metal ores. As of 1972 more than 40 percent of treated coal in the USSR was dressed by jigging.

Jigan overview ScienceDirect Topics

The elementary jig (Fig. 13.29) is an open tank filled with water. A thick bed of coarse heavy particles (ragging) is placed on a perforated horizontal jig screen. The feed material is poured from the top. Water is pulsated up and down (the jigging action) by pneumatic or mechanical plunger.

Low grade Iron Ore Beneficiation and the Process of Jigging

 · Fig 2 Principle of the jigging process. Though jigs are simple in operation the jigging process as a whole is rather complicated and strongly influenced by several interrelating factors (interacting variables or parameters). These factors are directly associated with one or more of the sub-processes into which the jigging process can be divided.
