At particle sizes larger than about 0-5 inch, froth flotation separation of polymers is difficult unless the density of the polymer to be floated is only slightly higher than that of the pulp.In most cases, the particles preferable are less than about 0.25 inch and most preferable are within the range of about 4 mesh to about 28 mesh.

In mineral flotation, rheological problems have limited the efficient upgrading of low-grade and complex ores.Since pulp and froth rheology are deemed to play different roles in influencing the separation performance, in this paper, a brief review on pulp and froth rheology in flotation is provided, with an objective of developing a basic understanding of rheology in flotation.
The usual commercial separation entails the lifting of a heavy metal sulphide away from a relatively light gangue by the agency of air bubbles rising through the pulp.This buoyancy results from adhesion of the particle to a comparatively large bubble.Contact angle mineral surface sodium silicate froth flotation.

Flotation frothers what is the function of frothers.The function of frothers in flotation is that of building the froth which serves as the buoyant medium in the separation of the floatable from the non-floatable minerals.Frothers accomplish this by lowering the surface tension of the liquid which in turn permits air rising through the pulp to accumulate at the surface in bubble form.
Therefore, the flotation separation experiments for artificially mixed minerals were performed under these conditions.1 c, the mo recovery in the froth products could reach almost 88.0 with a pb recovery of 7.6 and a pb grade of around 1.6 when pam-atu dosage was up to 1.
The separation efficiency of froth flotation was evaluated via the modified release analysis 6,32 this method measures materials separability by froth flotation from which the ideal flotation response of a given sample is derived.In brief, the modified release analysis consisted of two stages of separation.
