Flotation cells: Selecting the correct concentrate launder ...

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.

Slope of Flotation Slurry Launders for Froth Flow

Launders should have high enough velocities to prevent particles from settling, or if they fall to the bottom, to keep them rolling and sliding. The depth of water should not be much over the diameter of the largest rolling particles. For concentrates and heavy gangues slopes should be increased 25—100%. SPRAY WATER IN LAUNDERS:—While it is claimed that the quantity of water flowing with ...

Flotation Cell - an overview | ScienceDirect Topics

In Mineral Processing Design and Operations (Second Edition), 2016. 18.5.1 Batch Flotation. The concentrate obtained from a batch flotation cell changes in character with time as the particles floating change in size, grade and quantity. In the same way, the concentrate from the last few cells in a continuous bank is different from that removed from the earlier cells.
