Particle-bubble attachment in flotation froths -

1997-7-1  Abstract. During flotation, hydrophobic particles detach from the bubbles in the froth phase due to bubble coalescence, bubble bursting and froth overloading. While some detached particles drain back to the pulp phase, a fraction may selectively re-attach to the bubbles rising in the froth. This should result in grade profiles through the froth ...

Froth Flotation Research Papers - Academia.edu

Flotation of coal particles in MgCl2, NaCl, and NaClO3 solutions in the absence and presence of Dowfroth 250. Separation of naturally hydrophobic particles, such as coal, by flotation is known to be enhanced with the addition of salt solutions into the system. However, the exact reasons for this enhancement are not clear yet.
