In the process, a fine powder coal is produced, which requires further processing and recycling. This process is usually carried out by flotation methods, with flotation reagents to improve the separation efficiency of coal and impurities. Refined Coal is flotated, and the tail coal is setting down.

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 (Laskowski, 2001).
