The effect of air rate and froth depth on the entrainment factor in flotation has been extensively studied, but further investigation on the underlying mechanism for their effect is still required. In this study, flotation tests were performed at different air rates and froth depths in a 3 dm3 continuously operated cell using an artificial copper ore. The results showed that entrainment factor was affected by both air rate and froth depth, and the combined effect of these variables on…

Entrainment of Gangue Minerals in Froth Flotation: Mechanisms, Models, Controlling Factors, and Abatement Techniques—a Review

Entrainment is a process by which fine and ultrafine particles are transferred to the flotation froth from the top of the flotation pulp, and eventually discharge to the concentrate product, even

A Review on Froth Washing in Flotation

In the attempt to process lower-grade ores, mineral flotation has taken centre stage as the preferred recovery route. However, in many instances, the froth product does not have a high grade due to

Multidimensional Optimization of the Copper Flotation in a Jameson Cell by Means of Taxonomic Methods

Three factors were measured in the flotation process of copper ore: the copper grade in a concentrate (β), the copper grade in tailings (ϑ), and the recovery of copper in a concentrate (ε). The

The rapid depletion of high-grade rare earth elements (REE) resources implies that future supplies may be augmented with low-grade ores, tailings, and other unconventional resources to meet cut-off

Factors affecting the water recovery rate during froth flotation

An experimental examination of the effect of aeration rate, bubble size and froth height on the water recovery rate during froth flotation was carried out. It was observed that the water recovery

Measurement of Feed Water Recovery and Entrainment Solids Recovery in Flotation Columns

AbstractThe hydraulic entrainment recovery of gangue particles in a flotation process acts to decrease froth quality and is directly related to the quantity of feed water recovered. In this study,
