Flotation cells: Selecting the correct concentrate launder design

As with the internal peripheral launder the froth is pushed to the launder by the froth crowder. This design, however, provides more froth surface area. The external peripheral launder does not consume cell volume, so the effective cell volume for flotation is also higher. This launder is predominantly used on smaller TankCells.

Flotation Center Launder Upgrade

Optimal flotation recovery is achieved when these two processes work efficiently in harmony. The center launder upgrade is composed of three parts: Center launder; Outer crowder; Froth cone; Each tailor-made for your site to address your specific conditions. The center launder radically reduces the froth transport distance to the launder lip.

SELECTION OF MECHANICAL FLOTATION EQUIPMENT

Another advantage of the ank cell design is the ability to symmetrically alter the t froth surface areato suit the flotation duty at hand. This is normally done by adjusting the size of concentric crowders, and/or using different launder configurations. The net result is that the tank shape and design is for the intended flotation optimized duty.

A Review of Flotation Physical Froth Flow Modifiers

Therefore, a custom-made approach to flotation cell launder design is necessary to meet the duties observed/anticipated for each flotation cell within the bank. A change in feed ore conditions, e.g., if the new ore grade is lower than at the initial circuit design stage, it can result in low FCR in the bank of cells, which yields poor performance.

Review Scale-up in froth flotation: A state-of-the-art review

A launder is a channel in which the froth is collected after overflowing [48]. Standard flotation cells that only include a launder along the periphery of the tank can face the problem of having a stagnant froth zone at the centre (as shown in Fig. 8). This stagnant froth zones occur because of the long distance that the froth has to travel to ...
