Depending upon the medium used for beneficiation of coal, the various processes are classified as WET or DRY. Those processes using water as medium are WET processes and are known as Washing Processes. The coal beneficiation plants using wet processes are named as Coal washeries. For raw coal fines of –0.5 mm, the difference in surface ...

Aug 21, 2014· Patil and Parekh ( 2011) used a dry air table for processing of −6.3 + 1.4 mm coal from a mine located in Western Kentucky. The separation results show that the ash content is reduced from 27 % to 10 % with a clean coal yield of 75 %–80 % and the combustible recovery is 95 % with the ash rejection of 77 %–80 %.
