The end 11 of the froth removal device 8 separated from the axis 7 is shaped so that the end 11 of the froth removal device 8 will extend over the lip 12 between the launder 3 and the froth zone in the flotation cell 1. In the flotation cell 1 a froth regulating member 13 is surrounding the axis 7.

In froth flotation, separation between the valuable and the gangue minerals comes as a result of the attachment of hydrophobic particles to air bubbles. Considering the importance of bubble formation and bubbleparticle attachment, it is evident that the pulp phase facilitates the events for the most crucial requirements of successful flotation.

The bubbles surface and paddles scoop the froth off of the top of the cell. Product recovery rates in flotation are key to maximizing a mill's production. By utilizing superior level control, froth camera systems, reagent control valves, and advanced process control solutions, we can help you maximize your recovery rates.

As an important indior of flotation performance, froth texture is believed to be related to operational condition in sulphur flotation process. A novel fault detection method based on froth texture unit distribution (TUD) is proposed to recognize the fault condition of sulphur flotation in real time. The froth texture unit number is calculated based on texture spectrum, and the probability ...

Monitoring of the deviation between froth height and froth penetration allows the control system to track relative froth density all nonintrusively. Relative density data can be used to actively control density through a feedback loop, regulating forced air flow into the flotation cell.

Effective fault detection techniques can help flotation plant reduce reagents consumption, increase mineral recovery, and reduce labor intensity. Traditional, online fault detection methods during flotation processes have concentrated on extracting a specific froth feature for segmentation, like color, shape, size and texture, always leading to undesirable accuracy and efficiency since the ...
