In fact, producing coal from tailing is costeffective, economical and environment friendly. Reprocessing tailings of coal preparation plants is a new approach to coal washing industry. Gravity separation and flotation are the most common techniques in coal processing and recovery of coal from tailings in large scale (Wills 2011; John et al. 2002).

The operating costs of breaking coal particles into fine powder, to achieve optimum combustion for the boilers in a power plant, are made up of power input to carry on an energy intensive comminution mechanism and to overcome friction losses within pulverising machines. The operating costs also include the cost of the replacement of the processing system's components due to wear.
