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 ...
