What is Froth Flotation? wisegeek

Apr 24, 2019More recently, froth flotation is being used for treatment of contaminated water. The process used in mining begins with the mixing of finely ground ores with water into a tank or cell. A reagent is used to enhance the hydrophobic properties of the desired compounds to separate them from the residual substances which are more hydrophilic.

no flotation can occur. Contact between particles and bubbles can be accomplished in a flotation cell such as the one shown schematically in Figure 5. Figure 5 Simplified schematic of a conventional flotation cell. The rotor draws slurry through the stator and expels it to the sides, creating a suction that draws air down the shaft of the stator.

Principles of Froth Flotation. For successful exploitation of differences in surface properties most ore minerals must be ground finer than 4865 mesh. A light mineral such as coal (density circa 1.4) can be floated at 10 mesh, provided the bubble system on which it is borne is developed as a quiet layer of froth.

Flotation depends on the fact that the grains of some minerals, and especially of metals, differ in the degree to which their surfaces can be wetted by a suitable solution. The powdered product of grinding the ore is fed into a series of tanks called flotation cells which are filled with a solution containing various oils capable of forming a

Effect of impeller speed on properties of quiescent zone

Flotation process in mechanical cells is carried out in highly turbulent conditions. In this work, the impact of impeller speed on four characteristics of the quiescent zone, i.e. zone height, turbulence, solid percentage, and gas holdup, and their relationship with the entrainment is investigated, and it is shown why at a higher impeller speed, entrainment is not significant.
