Froth flotation - Wikipedia

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

In the mineral processing literature, the use of non-geometrical ratios and dimensionless numbers for the design of froth flotation tanks has also been proposed , , . These dimensionless numbers are detailed in Table 2. For example, the Reynolds number, Re, and Power number, N p (Eqs.

Froth Flotation | Hazen Research

Flotation techniques we have used in addition to the ordinary air-froth type include unusual procedures such as ion, precipitate, and agglomeration flotation using inert gas, air, or in situ gas generation. We have applied dissolved air flotation to special situations and are familiar with various forms of "piggyback" flotation procedures.

Model Predictive Control for Froth Flotation Plants - ABB Ltd

Froth flotation Froth flotation is a common method to extract a certain type of mineral from ore while depressing the amount of undesired minerals in the extracted concentrate. It is done by adding certain chemical reagents to selectively rendering the desired mineral hydrophobic. In a flotation cell, air bubbles then lifts the mineral.


CAVITATION NANOBUBBLE ENHANCED FLOTATION PROCESS FOR MORE EFFICIENT COAL RECOVERY Froth flotation is a widely used, cost effective particle separation process. However, its high performance is limited to a narrow particle size range, e.g., between 50 µm and 600 µm for coal and between 10 µm and 100 µm for minerals.

Eliminate Flotation Bottlenecks | E & MJ

Traditionally, mechanical flotation design has focused on the pulp zone or residence time, with little emphasis on the mineral’s froth phase. How it performs in the froth is critical—if the mineral doesn’t manage to travel up through the froth from the pulp and then from the froth surface to the launder, there is simply no recovery.

Froth flotation | ore dressing |

Froth flotation, separation of minerals differing little in density but greatly in wettability by surfactants that stabilize a froth formed on the surface of an agitated suspension of the minerals in water. See flotation. This article was most recently revised and updated by Erik Gregersen, Senior Editor.

+entrainment) and the mass of solids entering the froth by true flotation, i.e. collected mineral (particle-bubble aggregates). A froth flow number can assume any value less than, equal to or greater than one depending on the contribution of entrainment and true flotation. It was also


froth layer. Particles that are retained in the froth are recovered at the lip of the froth weir at the edge of the flotation cell. The recovery of the froth is accomplished by the natural mobility of the froth which causes it to flow over the weir and the recovery is sometimes assisted by mechanical paddles.


with conventional flotation) cannot be relied upon since of the froth near the froth-slurry interface varies over too wide a range. It is not generally possible to select the density of the float which will apply to all possible conditions. Moys and Finch (1988a, 1988b and 1989) have reported the use of
