Flotation Process
The behavior of coal in the flotation process is determined not only by a coal's natural floatability (hydrophobicity), but also by the acquired floatability resulting from the use of flotation reagents. The general classification of the reagents for coal flotation is shown in Table 6.1 (Laskowski, 2001).
