A Review of Flotation Physical Froth Flow Modifiers
Over the past few decades, the need to process more minerals while lowering capital costs has led to an increase in the size of flotation cells, e.g., 0.03 m3 to 1000 m3. However, this increase has created new challenges in the operation and design of industrial flotation cells, particularly in terms of froth removal, because the distance …

Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces …
Concentrate launder design: what is right for your operation?
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.
