1 Froth Flotation – Fundamental Principles Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached air bubbles are then carried to …

Flotation of coal using sea water The reason that sea water has been applied for coal flotation is mainly because in 1920 some coals were reported to be readily floated in sea water without the addition of reagents (collector and frother). In 1930's, the flotation of coal using sea water was further investigated by Russian researchers [8].

29-09-2003· Coal flotation system is quite complex since it involves multiple phases; coal particle, oil droplet and air bubbles, along with promoters and dissolved inorganic ions in water. A good understanding of these phases and the mechanism of the interactions among them is crucial for controlling coal flotation.
