While many types of agitators and aerators will make a flotation froth and cause some separation, it is necessary to have flotation cells with the correct fundamental principles to attain high.principles of flotation machines description,On the hydrodynamics of flotation machines - ScienceDirectFlotation is realized under highly turbulent flow conditions, so that turbulence may be process-determining, too. Because the principles of turbulent multi-phase flow have still not been fully worked out, one needs integral quantities to characterize the state of turbulence indirectly. To show the hydrodynamic conditions.PNEUMATIC FLOTATION - SAIMMPneumatic flotation - a modern alternative. Summary: Pneumatic flotation, a development of the past 10-15 years, is fundamentally different to pneumatic systems already known, particularly to column flotation. The basic principle, process kinetics, technique of the apparatus and economic advantages are presented. Results.

Froth flotation - Wikipedia

This slurry (more properly called the pulp) of hydrophobic particles and hydrophilic particles is then introduced to tanks known as flotation cells that are aerated to produce bubbles. The hydrophobic particles attach to the air bubbles, which rise to the surface, forming a froth. The froth is removed from the cell, producing a.
