An Engineering/Economic Analysis of Coal Preparation Plant

Although there is a myriad of approaches to coal cleaning, the technology is founded on relatively few basic physical principles. Nearly all physical cleaning techniques being applied today rely either upon specific gravity or surface characteristics to effect a separation of the coal from the undesirable constituents such as

(usually 1/4inch mesh). The largesized increment goes into the jig the remaining coal is sent to a separate cleaning circuit. The coal is dewatered on screens and in centrifuges, crushed to the desired size, and loaded. The jig makes the "equivalent" gravity separation on the principles of settling in rising and falling currents

Review of Jigging Principles and Control: Coal Preparation: Vol 11

The jig in its variety of forms applied in coal preparation has been a major unit in coal washeries for one hundred years yet the principles of jigging are still less well understood than those governing many other coal preparation unit operations. Jig control has also been viewed as an art rather than a science until recently.

Coal preparation plant Wikipedia

A coal preparation plant is a facility that washes coal of soil and rock, crushes it into graded sized chunks (sorting), stockpiles grades preparing it for transport to market, and more often than not, also loads coal into rail cars, barges, or ships. The more of this waste material that can be removed from coal, the lower its total ash
