Schubert (2008) suggests that pre-classification of the flotation feed into fine and coarse streams offers independent treatment of the size fractions. Power (or machine hydrodynamics) should be individually optimized to maintain solids suspension in the coarse stream, and maximize collision frequency in its finer counterpart (Schubert, 2008).

04/11/2013Decades 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.

18/07/2013Flotation works very well for particles that are typically in the range 20 to 150 μm in diameter, for base metal ores. In this range, it is possible to obtain quite high recoveries in conventional flotation machines. Outside this range, the recoveries decline progressively, whether it is with the very fine or thecoarse end of the size spectrum.
