Apr 25 2014 Froth flotation is a widely used process of particle separation exploiting differences in surface properties It is important to point out that overall flotation performance grade and recovery is a consequence of the quality and quantity of the solid particles collected from the pulp phase transported into the froth phase and surviving as bubbleparticle aggregates into the overflow

Decades of research have shown that the basic mechanisms of particle collection in the pulp and froth zones of a flotation machine are different based on size and liberation of the ore particles As a result using large vessels as roughers is a compromise since some ore particle types are recovered more efficiently at the expense of other types
