Flotation ore dressing Britannica

mineral processing: Flotation separation Flotation is the most widely used method for the concentration of fine-grained minerals. It takes advantage of the different physicochemical surface properties of minerals—in particular, their wettability, which can be a natural property or one artificially changed by chemical reagents.

Flotation separation of plastics can be enhanced by differences in hydrophobicity. In addition, flotation separation improves if the most hydrophobic plastic, that floats, has a lamellar shape and lower density and if the most hydrophilic plastic, that sinks, has a regular shape and higher density. The results obtained show that froth flotation ...

FLOTATION

Flotation is a process in Liquid-Solid Separation technology whereby solids in suspension are recovered by their attachment to gas (usually air) bubbles, usually with objective of removing the solids from the liquid. The particles most effectively removed are in the size range from 10 to 200 μm. The particle-bubble aggregates that are formed have a density less than the suspension itself ...
