The equipment is jig. Jigging separation process is quite simple, its equipment has high processing capacity, it is extensively used for coarse or mediumgrained ore, ... the large Baum jig (wind power driving water flow) used for coal preparation was invented. Jigging separation was essentially operational by the end of the nineteenth century.
An investigation into the relationships between the operating parameters of a jigging machine for coal cleaning and the quality of the cleaned coal was presented. The machine of interest was an OM18 highcapacity, three chamberjigging unit, with two chambers combined in the rock section and the third in the byproduct section.
The SKT12 model ThreeStages Jig Washer can realize the advantages of threestages jigging, and supported with secondary coal concentrate middling back washing process, which can meet requirement of improving final coal concentrate quality and quantity, it can increase coal concentrate recovery by at least 2%.
The coal beneficiation or coal preparation process separates inorganic impurities from raw mined coal, reducing the concentration of unwanted material or gangue and thereby providing improved combustion characteristics to the fuel produced. The commonly used beneficiation methods for coal sorting and processing include jig separation, heavy medium, and flotation.

A coal preparation plant ( CPP; also known as a coal handling and preparation plant ( CHPP ), coal handling plant, prep plant, tipple or wash 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 ...
Jigging is a densityseparation process which is widely used to separate heavier particles from the lighter ones. It is used for beneficiation of ore minerals as well as washing of coal. In its class it is by far the simplest yet a robust mechanical device that can treat comparatively larger size feed materials at higher throughputs.
