Jigging is an ancient but mature coal washing technology by gravity. It has more than 110 years history since the application of air jigging machine. However, because the theoretical research of jigging coal washing technology is still wandering at the hypothesis stage, it also seriously relies on operator's experience and skill, which results into no publicly recognized and uniform jigging ...

For centuries, jigging has been a workhorse of the mineral processing industry. Recently, it has also found its way into the recycling industry, and the increasing concerns related to water usage has led to a renewed interest in dry jigging. However, the current scenario of increasing ore complexity and the advent of smart sensor technologies, such as sensorbased sorting (SBS), has ...

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.

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.
