These factors make the entrainment of fine particles still occur during column flotation, diluting the quality of flotation concentrates and reducing the separation efficiency [14]. Recently, the Reflux Flotation Cell (RFC) was developed to overcome three major problems in the resources industry i.e., i) poor fine particles flotation, ii) poor ...

In conventional flotation cells a certain amount of energy is required to meet the basic requirements for flotation (air dispersion, solids suspension and particle-bubble collision). This paper investigates how that energy is dissipated in the flotation cell to determine the most efficient use of the imparted energy.

Variables of hydrodynamics are equally important as those of surface chemistry in determining the efficiency of froth flotation processes. In a mechanical flotation cell, macro hydrodynamics is responsible for solids suspension and aggregates transport, and micro-turbulence plays an important role in the sub-processes of …

The high efficiency of a froth flotation process is limited to a narrow particle size range. Nanobubbles integrated into a specially designed flotation column expanded the particle size range for effective froth flotation as a result of increased probabilities of particle-bubble collision and attachment and reduced probability of detachment.

A microbubble-based separation of oily wastewater is widely used because of its high efficiency and low cost [1]. Using a flotation cell or column, microbubbles generated by bubble generator system and oil droplets formed the air/oil droplet aggregates after collecting and adhering, then rising to the top of flotation units, as a result of oil ...
