Losses In The Coal Supply Chain

Losses In The Coal Supply Chain

Coal processing by separation at preparation plants refines coal further and is where most of the mass loss occurs value is added by reducing ash content and improving heating value thus providing a much more saleable product for the market as soon as the coal leaves the mine mass loss can
