Minerals Special Issue : Fine Particle Flotation

Froth flotation is the most economical method to separate minerals in ores. However, the complexity of new ore bodies requires fine grinding to liberate valuable minerals, which produces particles with sizes too fine for an efficient mineral flotation and separation.

Production and Processing of Fine Particles

The present study has resulted in a new process of fine particle flotation and its characteristic is returning concentrate into slime. The new process has been used for the flotation of hematite from Anshan mines, copper oxide mineral from Tonglushan mines, lead-zinc slime from Fankou mines and tin slime from Dachang mines.

The limits of fine particle flotation ScienceDirect

01-04-2010 Understanding the limits of fine particle flotation is the key to the selective separation of fine mineral particles. Fine particles have low collision efficiencies with gas bubbles and float slowly. There has been a great deal of work aimed at overcoming the inefficient collision of small particles with rising air bubbles.

Fine Particle Flotation

Floating “fines” differs from floating “sands” because the fines have a much larger surface area compared to their mass. The forces that arise from this large specific surface are the key to under standing the behavior and treatment of fine particles. Though the nature of these forces is not thoroughly understood, enough work has been done to give a qualitative picture of what is

Flotation Kinetics and Fine Particle Flotation

As with all physical and chemical processes flotation is a rate process governed by kinetic parameters, which are determined by several factors including the chemistry of the mineral-water interface, particle-bubble collision efficiency, and the strength of attachment of particles to the bubbles.

The Limits of Fine and Coarse Particle Flotation

For fine particles, the flotation limit is dictated by the energy required to rupture the intervening liquid film between the particle and bubble. Flotation of very fine and large particles is facilitated with small bubbles and high contact angles. These results greatly extend our earlier observations and theoretical predictions.

A NEW PARADIGM IN SULFIDE PROCESSING BACKGROUND

The underlying mechanisms responsible for the decline in flotation recovery of very fine and very coarse particles have been extensively discussed in the technical literature. For finer particles, lower recovery is typically attributed to low bubble-particle collision rates that reduce the probability of attachment.
