The effect of coal rank (wettability) on flotation was extensively studied. Wheeler (1994) showed that while MIBC is an excellent flotation agent for easy-to-float bituminous coals, it looses quickly its effectiveness when used to float lower rank coals. In this latter case 2-ethyl hexanol was found to be much better.

Froth flotation is an effective separation process for fine coal upgrading, which occurs in the gas-liquid interface. According to the differences in the surface properties of coal and gangue minerals, the hydrophobic coal particles can be separated from the pulp by their attachment to the rising air bubbles that form a particle-rich froth on the suspension surface …
