The invention is a process for recovering coal from raw coal which comprises subjecting the raw coal in the form of an aqueous pulp, to a flotation process in the presence of a flotation collector, and a flotating amount of a flotation frother which comprises the reaction product of a polyhydroxy C 1-20 alkane or polyhydroxy C 3-20 cycloalkane and propylene oxide, or a mixture of propylene ...
Separation of unburned carbon from fly ash is an efficient way to achieve a higher efficiency in the utilization of waste fly ash and greater economic and environmental benefits.
What Is Coal Preparation? • Coal preparation is the removal of undesirable material from the Run-of-Mine (ROM) coal by employing separation processes which are able to differentiate between the physical and surface properties of the coal and the impurities. Through coal preparation.

The high belt speed also enables very high throughputs, up to 40 tons per hour on a single separator. By controlling various process parameters, such as belt speed, feed point, electrode gap and feed rate, the device produces low carbon fly ash at carbon contents of 2 % ± 0.5% from feed fly ashes ranging in carbon from 4% to over 30%. Figure 1.
