Fine coal washing Spiral + Jameson or Microcel technology. Limited use of froth flotation for metallurgical coal. Dewatering Coarse medium size Vibrating or scroll type basket
Currently 4 prominent/established technologies for coal washing are available in India. These are Barrel Washer, Heavy (Dense) Media Bath, Air (Pneumatic) Jig and Water (Batac) Jig. We expertise in all these technologies and use them at least at one of our plants depending upon the requirements and available coal quality.

Jigging is an ancient but mature coal washing technology by gravity. It has more than 110 years history since the appliion 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 ...
The benefits of this technology. The allair ® air jig helps coal producers by turning increased quality and productivity into a competitive advantage. Given the low costs associated with the allair ® air jig, coal that would previously have been dumped or not mined at all as a result of its high ash or sulphur content can now be turned into a marketready product through economical processing.
A batac jig is a variation of this design that uses an air chamber below the perforated plant to trap air and create the pulsing action. Jig installations require specific conditions in order to be effective and are significantly less efficient than competitive heavy media processes. As a result, the use of jigs for coal cleaning has declined ...
· Several dry coal separation technologies, such as, AllAir ® Jig (allmineral ), Air Dense Medium Fluidizied Bed (ADFMB), Tirboelectrostatic Separators, Rare Earth Magnetic Separators (REMS), and Xray Sorting technologies, were proven effective in terms of separation to achieve lowash products for coarse to midsize fractions (Dwari and Rao 2008; Zhao et al. 2014).
coal preparation plants, the separation relative density (RD) for deshaling is higher with a typical target of RD = or greater (Honaker et al. 2008). Several dry coal separation technologies, such as, AllAir® Jig (allmineral ), Air Dense Medium Fluidizied .
Coal beneficiation by jigs. Jigs have been in use in coal washing for many centuries. In the United States of America, for example, about 37% of coal beneficiation plants clean their coal using jigs (Mehrotra and Mishra, 1997).
PNEUMATIC JIGS Raw coal fed on to the vibrating bed having crosswise and vertical slope. Air supplied through air holes in the beneficiation bed which agitates the raw coal resulting in stratifiion of coal as per its relative densities lighter coal forms the upper layer and heavier coal forms the lower layer. Upper good coal goes to
