Flotation Developments Best Practice International Mining

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.

flotation – Mining Mill Operator Training

Froth flotation is a physicochemical separation process. Separation is principally based on differences in surface hydrophobicity. However, particle size and density have a significant impact. Initial flotation patent and application was developed for graphite by the Bessel brothers (1877). Similar to graphite, coal is naturally hydrophobic.

Frother Particle Size and Selectivity of Sulfide Mineral ...

A very important factor in froth flotation is the use of surfaceactive chemicals to form a froth in which minerals or coals are retained, thus allowing for valuable component enrichment. Despite the importance of frothers, surprisingly little systematic scientific work has been performed with the goal of quantifying frother mechanisms and the influence of particle size on frother performance ...

froth flotation size

The particle size to which the ore is ground depends on the nature of the ore. The grind must be fine enough to liberate the mineral grain from associated rock, but producing too small a particle size is both expensive and detrimental to recovery. Froth flotation is generally limited to size fractions between roughly 65 and 100 mesh. Get Price
